I'm sure it is in footnote in datasheet
No, they really are that grimy and will pull tricks like this until you call them out on them.
They will then issue errata later, after millions of devices have been shipped.
Readit NewsI've noticed that the sentence “Compliant with RVA23 excluding V extension” has apparently been a bit confusing to some reporters in the tech press lately.
It means that the UR-DP1000 chip would have been RVA23-compliant if only it had supported the V (Vector) extension. The Vector extension is mandatory in the RVA23 profile.
There are other chips out there even closer to being RVA23-compliant, that have V but not a couple of scalar extensions. The latter have been emulated in software using trap handlers, but there was a significant performance penalty. V is such a big extension, with many instructions and requiring more resources, that I don't think that it would be worth the effort.

This is a thing SoC vendors have done before without informing their customers until it's way too late. Quite a few players in that industry really do have shockingly poor ethical standards.

I sometimes think that my 40" is too much because the extra space just ends up hosting distracting junk like Slack.
I also have a mild take that large screens make screen real estate cheap so less thought goes into user interface design. There's plenty of room just stick the widget anywhere!
This is why multiple monitors win: put the distractions on a whole other screen.

I wonder how different street legal in Canada is from in the US, given the connectedness of manufacturing and markets.
Maybe they will be banned for "national security".
EDIT: specific statements here: [https://news.ycombinator.com/item?id=46651051]
Yes, I should have linked that story myself, it's one of the things that provoked the comment.
There are differences for street legality mainly around importing older cars which meant at one point the JDM scene in Canada had access to a lot more cars than the US did.

I'm also curious to see if we will see more "no drive zones".
We see this in other domains: I recently talked to someone from an asset inspection (think flying around bridges to check for fractures) company. They can't use DJI drones because of security concerns.
What has astounded me about all this is the extent to which so much of our industry fall crisply into one of two groups: 1. Chinese stuff is cheap incompetent rubbish anyway, anyone near it is by definition a loser, so who cares? 2. Chinese stuff is perfect, amazing and we should just stop doing everything and buy what they're selling. They'll totally open factories here and give us jobs too!
The actual reality, which people like your asset inspection firm are dealing with, is the Chinese have leapfrogged the west in so many important respects, but to preserve security we have to live in an expensive technological backwater since the leaders of our society are so resistant to internal disruptive competition that may result in other people displacing them.

These cars are street legal in the US. Ford's CEO used one as a daily driver. Unless the car stays permanently it wouldn't be counted as an import.
Aside from everything else, Ford's CEO is not going to be subjected to the same rules as you or I.
A reality of all gov regulators is a degree of flexibility with respect to people undertaking genuine R&D in an upfront and responsible way.

While Canada might have taken a step like this eventually, Trump being Trump made it far more likely due to his desire to alienate Canada.
Now it is likely that Chinese EVs will drive on US roads from Vancouver, Montreal and Toronto into the US and US citizens will see for themselves. I'm not a fan of cheap cheap labor in that it reflects poverty that shouldn't exist in the modern world, but the strategic insistence of Detroit to produce expensive, low-efficiency, low-capability SUVs will start to backfire.

It is not clear they will be allowed to cross the border in these cars.

What will be interesting are the restrictions on where the BYD vehicles are allowed to go.

They can only do JS cyberattacks?
Maybe they need to use RISC-V assembly ;).
This is the sort of comment that makes people lose faith in HN.
There totally are cases where it's intentional, and no they are not discussed on the internet for obvious reasons. People in the industry will absolutely know what I'm on about.
