However, the SHA-1 hash is not actually essential to git. In the git
world, there is only content and every object is identified by its
content. Now, to identify an object, it would be pretty cumbersome to
have to write out the contents, so we abbreviate the contents with a
hash.

So, the hash or object name or object id or whatever you want to call
it isn't even an essential part to git. It is a convenience.

In that sense, I think that '[cryptographic] hash' is the right term,
because the others ("object name" and "object id") seem special. A
hash is not special. In fact, the documentation should read "For
convenience, the git tools refer to objects using the hash value of
their contents". You see? It's not essential.
