You said:

 "upgrading the system compiler is a serious decision.  Installing a
 newer compiler could easily break the build of several important
 packages (...)"

And I'm telling you that the packages in question don't upgrade
the system compiler at all.  There's no risk of "easily break"
things.

Of course people can do all sorts of crazy things, even
"sudo rm -rf /"

But we're not in the business of protecting against all foolishness.

No you don't.  The system one is still the default.

There's nothing complicated here.
