Are you willing to build all 6100+ ports to verify all of them are okay with 
+with_default_names?

Also, note that some of these ports are dependencies for other ports, so it 
may not simply be a case of "you wanted it, so you must want it as the
default".  For example, I have m4 and gsed installed solely as dependencies,
and I believe that's how I've ended up with coreutils before.
