Yeah, I also think that six months is a bit short, but three years on
the other hand feels like it will cause quite some pain on our side. My
plan is shooting for roughly one year of optional support, which is
still way shorter than the three years you mention.
How would you feel about:
- Pinning a date for Git 3.0 at the end of next year and tying
mandatory Rust to it.
- Guaranteeing at least one year of security backports for 2.99 (or
whatever the last release before Git 3.0 is).
- Explicitly stating that if anybody requires to maintain that version
afterwards, we are happy to let the community maintain that branch
going forward.
That means that we stop supporting 2.99 in a bit more than ~two years
from now, but we don't fully close the door on it if people still rely
on it.
