It's only a nightmare if the flags in question are user-frobbable.  If
they are all nailed down in the DISTRO configuration (which
DISTRO_FEATURES certainly ought to be), and those folks who want to
build compatible binaries just leave them alone, then there oughtn't to
be any real problem.  To that extent it doesn't really seem any
different to the choice of compiler or tuning flags or glibc version or
any of the other ways in which you can already produce incompatible
binaries by flipping the wrong switches.
