Currently git doesn't advertise that archive creation is stable
right[1]? So I wrote that with the assumption that this new
compression would only be used when making a new archive with a
hypothetical new '--stable' option. So historical reasons don't come
up. Or was there some other form of history that you meant?
I'm just trying to point out here that stable compression is doable
and doesn't need to be as complex as specifying a stable gzip format.
I am not even saying git should just do this, just that it /could/ if
it decided that stability was important, and that doing so wouldn't
involve the complexity that Avar was implying would be needed. Simple
compression like LZ variants are pretty straightforward to implement,
achieve pretty good compression and can run pretty fast.

[1] if it did the issue kicking off this thread would not have
happened as there would be a test that would have noticed the change.
