Yeah this came out of the IPFS camp, might be sensible though to use the same numeric id numbers for the hashing algorithm ids though all other things being equal.
Generally, and this is just my gut feeling, I think that for any hash code written to disk or stored in some way having an identifier for the hashing algorithm used is such a common bite you in the ass later thing that it makes sense to always just do it from day one. To that end it’s easier to do day one if everyone agrees to a standard set of numeric codes.
Multihash is the standard set of numeric codes for different algorithms I am aware of.
Unifying here might allow git objects to be served natively over IPFS.
Just a quick note, while we still would really love to have git use multihash. You can already serve git objects natively over ipfs via: https://github.com/magik6k/git-remote-ipld

Yes, that's the basic idea of all multiformats: "it's never gonna change" is considered harmful.

There's no good examples for Git specifically yet, but there's a good bunch of working code for transporting e.g. Ethereum and Zcash transaction blobs over IPFS. For Git it's in principle the same: import the raw object into IPFS, and starts addressing it with /ipfs/<git-cid><original-git-hash>
