I think I know the answer, but I think it would be helpful to discuss
the underlying motivations too. I.e. an obvious alternative is "why not
just get this information out of git show/log then?".

The "I think I know the answer" being that I suspect this is to cater to
gitaly having persistent "cat-file" processes around, whereas for "git
log" it would entail spinning up a new process per-request.

But maybe I'm missing something :)

So not as a blocker for this change, which I think can be made small
enough to be justified in cat-file, but just for context: If "git log"
had a similar --batch mode, would there be a need for this change, or is
this just adding a common case to "cat-file" to "tide us over" (as it
were) while that sort of thing doesn't exist yet (and maybe never will
:()?
