bpo-34790: Implement deprecation of passing coroutines to asyncio.wait() by aeros · Pull Request #16977 · python/cpython
The PR should not be backported to 3.8, right?
Yep, that's why I did this one separately from #16975, which only fixed the 3.8 whatsnew entry based on Yury's suggestion. Otherwise, the changes would've been combined into the same PR.
It raises new deprecations that were absent in 3.8.0; adding them in 3.8.1 is confusing.
Agreed, I'm starting to realize that we should try to avoid implementing significant deprecations partway through a major version (3.x) when possible. It would more likely comely across to users as a surprise and lead to some confusion rather than being overly helpful. For example, if users have already ran their tests with warnings enabled and resolved any deprecation warnings for 3.8.0, I don't think it would be a great experience for them to encounter a bunch of new ones in 3.8.1.
