interesting to see /dev/null uses UUIDv7 and not git's SHA-1 or 256 for commit identifiers

Interesting, would this have been a deliberate choice? For any other platform I would say, UUID is a perfectly fine choice. But for /dev/null a SHA based commit identifier would have made sense. Maybe they avoided it to allow edits to messages at some point? Without messing up published links and having to modify database identifiers? @tom anything in your knowledge window about this?
