[Rpm-maint] Filtering blues

I'm somewhat unhappy with current filtering mechanisms, or perhaps just
not clever enough to use them in the right way.
In a very normal usecase, I have a private library from which I want
to block the Provides: This is simple enough using
__provides_exclude_from <some library.so>. Here the story should end, I
have filtered the Provides: the way I want..
However, the package is now un-installable since the depsolver Requires:
the symbols I just filtered. This means that I have to filter the same
symbols which I blocked using __provides_exclude_from from the Requires.
But this is not a simple __requires_exclude_from, because that will
filter *all* dependencies from my library. So I have to use
__requires_exclude, and enumerate each and every symbol catched by
__provides_exclude_from in a long list.
It definitely doable, but it feels clumsy and error-prone. I miss an
elegant way to do this, something like __provides_requires_exclude_from
<file-match> which filters the symbols in <filematch> in both Requires:
and Provides, or, perhaps better, a way to refer to the symbols in a
<file-match> found by __filter_provides_from so I can use them in
But it might be that I just don't understand how to use those macros.
It's not that intuitive, really.
