I agree with the problem statement, but not the solution proposed. I
don't think finding all dependencies QUIETly makes sense. That has other
side-effects.

Did you/will you consider changing the feature_summary implementation to
filter them out another way? How does feature summary work? Can the
find_dependency macro somehow omit entries from feature_summary?
(without affecting other direct find_package calls?

Thanks,
