Multihash is a rather nifty format for hashes, where you can distinguish between e.g. a SHA1 and a Blake2b: https://multiformats.io/multihash/ It originates from the IPFS project, where they want flexibility in how they implement content-addressable storage.

Git repositories have the lovely properties that deletes aren't propagated. Shared/cloud storage sync deletes across devices. Accidentally deleting content in a local git repo, and even pushing it, is a safe operation.

GitHub actions is really polished: it groups outputs by command, has good support for build matrices, and a growing ecosystem. It's a big feature that lets GitHub avoid being a simple git storage service. Issues are nice, but much more easily migrated.
