There are so many neo-shells that go crazy with colors, autocompletions, & SQL-like features while the most basic problems (like handling of newlines/spaces/international chars) are mostly swept under the rug with -null/-print0, which is more hack than solution. I think Tom Duff's rc shell was an excellent start in that direction, which sadly went nowhere.

This is woefully misguided. Half the time passing it to the shell is explicitly a feature, e.g. `popen("gzip > foo.gz")`. If you have user input you should always sanitize it regardless of API.
But `ssh` does deserve all the shame. It's a pity the real problems are hard to find in an article full of nonsense.
Note also that if you're using a deficient shell that supports neither `printf %q` nor `${var@Q}` it's still easy to do quoting in `sed`. GNU `./configure` scripts do this internally, including special-casing to only quote the right side of `--arg=value`.

Pls elaborate. Seems like a decent list of shell gotchas to me.

To improve your health never start with adding a chemical!
Instead remove chemicals and toxins first and foremost.
This is true. I've had so many problems where the pills and creams were time and money down the drain, and the solution was to cut something out of my diet or lifestyle. Less is more.
What is YSH? https://oils.pub/ysh.html
I am writing a quoting module now, but the key point is that it's a powerful enough language to do so. It is more like Python or JS; you don't have to resort to sed to parse and quote strings.
I posted the quote-argv solution above -- in YSH it will likely be:
But you can write such a function NOW if you like---
quote.sh follows the (subtle) idiom of replacing a single quote ' with
which means it works on systems with remote POSIX sh, not just YSH !e.g. "isn't" in POSIX shell is quoted as
which is these three word parts: YSH also has:- JSON, which can correctly round trip every Unicode string, without writing your own parsing functions
- JSON8, an optional extension that can round trip every byte string you get from the Unix kernel
