At haikuports we are in the process of removing python3.7 from the recipes and adding python3.10 to them.
As with always there has been a discussion to remove python3.8 also, (python3.7 will soon see EOL), for python3.8 we are holding of for about 6 months so users still using python3.8 can update their work to use the default python3.9 now.
Any comments are welcome here and at the issue at haikuports: Drop support for Python 3.7 · Issue #8025 · haikuports/haikuports · GitHub
@BiPolar is already re-working some recipes like I did when we dropped python2.7 in most of the recipes. (happy hunting there ) (but you want be alone in this).
