The correspondong scenario is a Debian/RedHat/Slackware *binary package*.
That is of course installed into /usr.

End users should only compile from source as a last resort.
Otherwise, they should get an updated package from Debian/RedHat/Slackware.

Agreed.  And it is more difficult if gcc is installed in /usr,
for any Linux system based on Debian/RedHat/Slackware, unless
it is installed as a package upgrade.
