I remember this discussion well. It was for those "stubborn" people who wanted a clean system. I added to the discussion by saying "what about embedded systems people where every file counts because of inode and block allocation constraints" and the answer was INSTALL_MASK, not a USE flag, for the reasons Rich stated. This was to create a openrc/systemd agnostic system.
