I thought this would be a snark but it's an extremely well put together argument against the "Hashmageddon".
If you're replacing the weakness of SHA-1 just by going to another algorithm, you better be prepared to go to the next one when sha256 collisions happen, and it doesn't sound like git's design would be easy to modify for this type of crypto agility.
I do like their proposal for using signatures to establish trust and allow swapping sha256 for whatever comes next.
