This point was debated then, and there were good reasons why a lot of users can't/won't do this. The two I remember are (1) a lot of non-technical users use apps that aren't getting upgraded, and so will always emit those warnings, which often scare or confuse them, and

If folks get scared away from running unmaintained software, that's a good thing, not a bad thing.

(2) doing it in PYTHONSTARTUP is indeed global, and the kind of people who use interactive sessions typically want to see those warnings, but only some of them and only sometimes.

Then that's a good motivation to learn how to manage which deprecation warnings they actually see.

Cheers, Nick.
