Not unless they are actively known to break.  People get huffy about it
because even if it is known to have problems it doesn't break *their*
particular configuration.  I'm getting to be of the opinion that people
who compile modern kernels with ancient compilers and expect it to work
are suffering from some particular kind of insanity -- it's nothing the
distros do.  The only exception are embedded people who compile with the
latest 3.4 gcc; they have explained they do so because newer gccs have
too many dependencies (the actual compiler, not the generated code) and
for speed.
