Thanks for that viewpoint. As a compiler optimizer junkie, I don't
really follow things on the RPM side, so hearing about that process has
played out is useful.
For the record, Mark has started implementing DWARF-5 support in
dwz:

I think I would rather like to see a Change proposal to switch to
DWARF-5 for Fedora 34, especially since it looks like dwz will be
ready for it.
Yea, I think moving to dwarf-5 would be a good step forward. ISTM we
ought to do a test mass build with dwarf-5 by default. I'm currently
testing some bits for other GCC developers, but ought to be able to do a
dwarf-5 spin in a week or so to get a sense any notable fallout.
