I am with David here, I think it's more important to get something
working into users hands first, than trying to aim for the perfect
solution. So while these cross-building efforts are super interesting
and also useful, I think we should aim for native builds reproducible first.

This is in a way similar to us recommending to achieve a reproducible
Buster Debian release with deterministic pathes first, IOW to do the
rebuilds in the same path than the original build was done. We do want
to aim for the much better goal to be able to reproducibly rebuild in
any path, so we do test this when testing Debian unstable, but
personally I dont have much hope this is achievable by, say, 2023,
rather 2027 or so. 

And I want reproducible Debian *much* earlier, so I advocate for doing
rebuilds of buster in those same pathes... I know this is "wrong",
packages should be reproducible in any path, but I want reproducible
Debian *before* that is the case.

That said, if you want to work on either reproducible cross builds or
path independent build resulst, yay to you!
