Deprecations via warnings don't reliably work anywhere, in general.

If you are a good developer, you'll have extensive unit test coverage and CI. You never see the unit test output (unless they fail) - so warnings go unnoticed.

If you are a bad developer, you have no idea what you are doing and you ignore all warnings unless program crashes.

Author here! Agreed that are different levels of "engaged" from users, which is okay. The concerning part of this finding is that even dependent users that I know to be highly engaged didn't respond to the deprecation warnings, so they're not working for even the most engaged users.
