The requirement still specifies a specific major version of GCC. It just means the dependency isn't broken every time Ubuntu bumps to a new minor release or even just makes a minor change to the package alone.

All we get from this exact version requirement is sporadic breakage. If we truly want a static version of GCC, we need to provide our own as we do with the JDK.
