I see no reason why the default compiler shouldn't be the fully featured
one and then distros and users can turn off the bits they don't want if
they choose to.

Is that the issue you mean or is there a concern I'm missing?

I can see the other side though, its a pain having to fight fortran
build failures when upgrading the compiler if you never use fortran. Its
this point where it becomes a pain to have so many old versions of
things as this would be much simpler to arrange and maintain if we had
less gcc versions. I worry about trying to add gcc-runtime to OE for
this reason.
