I can't answer for Tulio.

In my own past experience it was simply a problem of expectations. When I've
written commit messages it was with my current understanding of the patch, and
sometimes that produces terse commits that don't contain enough information to
help downstream distribution maintainers or don't explain enough of the
solution's constraints.

Hopefully this verbose writeup here in the bug will help other distribution
maintainers get past the build issues.

I empathize with your pain though, we had to go through the rebuild loop in
Fedora 27 for our mass rebuild.

What else can I do to help?
