No one is arguing for dropping the build path from .buildinfo files.
As we discussed at the reproducible summit, .buildinfo files serve two
0) they document the environment used during a specific build, to a
level of detail that should make it at least possible to reproduce
1) they also document things that should *not* be necessary to
reproduce the build, but might be under some circumstances, or for
I think the build path falls into category (1) here.
In an ideal scenario, we could have two buildinfo files with variations
on the build environment (buildpath, minor versions of build-deps, etc)
and *still* have reproducible binary outputs. This would let us know
that the variations in question are not things that cause variation in

yes, that would be great!
