[Nix-dev] fetchgit - why sha256 protection?

Again: I'm not talking about the current state. I'm aware about how it
works.
I'm talking about:
"Does it make sense to introduce a special fixed hash for git repos" or
"what about implementing git checkouts natively so that passing the
git's hash is enough"?
git sources are very common today.
