Ubuntu ships with a default GCC but you can also install other GCC's
/usr/bin/gcc versus /usr/bin/gcc-4.2 versus /usr/bin/gcc-3.4 etc
It doesn't seem very onerous (on Ubuntu) for the end user to do this.
I'd think other distros also do this. I have no idea how onerous it is
for the distros to provide this service.
