It's not really a question of good enough, if you use the mtime of the driver on all builds, then *every* time you rebuild the compiler, you invaldate all the cache objects that have been built with it. That can have a major impact on port building, and it's in things like "portupgrade -rf gettext" where ccache is most significant. Using the hash avoids that problem.
