To that end it’s easier to do day one if everyone agrees to a standard set of numeric codes.

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

IPFS can already do that thanks to the CID format: https://github.com/ipld/cid

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>
