Yeah, kinda agreeing here. The hash length will need to be increased anyway, but concatenation of SHA1 and SHA256 will be 104 bytes in total when displayed (40

Yeah, kinda agreeing here. The hash length will need to be increased anyway, but concatenation of SHA1 and SHA256 will be 104 bytes in total when displayed (40 + 64), which is a lot. It may be a better to display SHA-256 commit hashes, but accept SHA-1 hash prefixes for old commits. It may be confusing for git to accept hashes that aren't visible in `git log`, but it's probably for the better.
