Of course, they do: you have a newer compiler on your system, which is
about to be used for building some packages.
> There's no risk of "easily break" things.
Of course, there is: the new compiler will do that.
That one can go back to the old one doesn't help at all, because that
was also possible without a parallel installation: just uninstall the
new one and install back the old one.
Organizations rarely do this stuff. You want to install a compiler
and let users use it without complications. Most of your users aren't
hackers, they have no idea how to debug a package build problem. They
will come back to you expecting that you fix the problem for them.

I respectfully disagree. We most probably have very different
experience here, and very different users to deal with.
