Imagine, we have pythonXdist(foo) extracted from PyPI metadata, but in
Fedora we still need to add some more BR for that, so we add it. When
new release comes (still without added BR in upstream) rebase-helper
will not be helpful. It can change only version of spec.
This is a self-inflicted problem arising from our current tooling
design, though, since "generate-and-edit" isn't the only way to
supplement upstream metadata: we can also design spec file generators
to accept a supplemental config file in addition to the upstream
metadata.
If we're using that alternate model, then rebase-helper can have a
much easier time of things, since it isn't trying to edit a previously
generated spec file, it's just generating a new one based on the new
upstream metadata and the old supplemental metadata, and seeing if the
result still passes CI.
Cheers,
Nick.
