Guido van Rossum <guido at python.org> added the comment:

I haven't followed this precisely, but I recall that when we first made PEP 563 the default, we had to fix a number of bugs in various library modules (e.g. inspect) that were only apparent when `from __future__ import annotations` was used. I hope we're not throwing away those bugfixes. Hopefully Batuhan has a recollection of what I am thinking of, there was some significant delay while we figured out what to do about some of these.
