Hmmm, our Apple Silicon blog's philosophy feels very relevant here: https://blog.pantsbuild.org/how-we-added-apple-silicon-support-to-pants/

However, successful open source projects are full of tradeoffs between purity vs. pragmatism. We often remind ourselves "Do not let perfect be the enemy of good", and we are passionate about prioritizing an excellent experience for users.

I do think it's bad to completely stop supporting Py2 out right, at least for the next year. But I believe that this could be a pragmatic compromise that unblocks improvements for the vast majority of users, while still giving a decent experience to Py2 users: https://pantsbuild.slack.com/archives/C0D7TNJHL/p1625860941311500?thread_ts=1625860065.310100&cid=C0D7TNJHL
