FWIW, to me, the impact of modular X had been way more severe than that
of GCC-4.1.

Speaking as maintainer of SIMVoleon, I can tell you why I haven't
rebuilt it yet:

* Initially, there had not been any need to rebuild it. If I hadn't used
%{?dist}, you wouldn't even know this package had been built for fc4 and
it would remain functional until an incompatibility hits.

* Later, modular X11 detonated in Rawhide and broke srpm/rpm
dependencies of SIMVoleon and its dependencies, both in Core and Extras.
Esp. getting the broken packages in Core fixed was a true PITA had
caused major delays in fixing the packages in Extras.

* Midst all this, GCC-4.1 dropped into Rawhide, breaking source code
compatibility (SIMVoleon is C++).

I.e. in a nutshell: So far, Rawhide has been too volatile to me to make
rebuilding SIMVoleon feasible.
