Right, we don't have to be religious about the LTS deadlines and I was not pushing it for 15y old servers. In my experience though I still see actively used systems based on rhel 8 / ubuntu 20 around so the plan to cut them now seems premature even when considering >2y of our release cycle. > Another important distinction to make here is in these arguments are if > the issues are related to the users or to the developers? > > Because sometimes in the conversations they are mixed and they clearly > correspond to different concerns. > > For developers the releases correspond to what exists now, while for > users the concern are the distributions that will be available when the > first stable version is released.

If you maintain that it's easy for on rhel 8 system to upgrade / run in parallel python >= 3.8 we could perhaps bump to 3.8.
