That said, in my personal experience with uv, it solves nearly all of the problems I've come across that were created by other python package management tools. It seems to have been very thoughtfully designed and I think there's a strong chance it'll become the standard, and that there won't need to be more standards after this. We'll see!

I think this is the reason, but its more nuanced than this. Management finds in-office employees easier to manage. They are more likely to attend meetings, participate in team communication, give status updates, etc. There's much less of a question around "is this person doing the work" if you can see them doing something that looks like work in the office. If you are blocked or are blocking someone, it's a tap on the shoulder instead of sending a message into the ether.

Management of remote employees is a huge information gathering exercise - very little of the above information is proactively surfaced to you, and instead you have to go looking for it. Frankly, it's just a lot more work for managers.

I realize the above may not be fair to employees, or that the perceptions of managers accurately resemble the truth - just stating what I think is going on.
