I think currently we have version 1. But we don't advertise it, so
I'll call it 0
(the default or unadvertised or however you name it. 0 as in "unsure" maybe)

I thought about future proofing this version a bit. Say version 2 is bad because
I don't have the experience of 10 years Git nor of maintaining large
projects and
you want to make a version 3 soon. And this would support that just fine.

The meaning being: Any version except 0 should have a dedicated
extension -${version}
The 0 is left out for backwards compatibility.

So in a later patch where we want to introduce force-using of old
versions  you could
configure upload-pack to be explicit upload-pack-1. The upload-pack-1
version is not
yet there with this series though.

Oh! I see here you would count the current one as 1, which has no
number extension,
and any further would have a -${version}. That would transport the
intention much better
I guess.
