This would be best, though it's a big ask, when everyone has gone from self hosting plus a sprinkling of cloud services, to only cloud services and no remembrance of how to self host.

I used to run a git server for all my main projects, and mirrored public ones on GitHub. Then the convenience of GitHub lured me in, to the point I shut down my private git server 5 years ago.

Now I kinda regret that decision.
