I'll give an example where revbumps are significantly inferior to --changed-use. The selinux useflag is hardmasked in all profiles except the selinux ones and 99% of users do not run selinux. I regularly add "selinux ? ( sec-policy/selinux-foo )" to RDEPEND of packages. With --changed-use, only the people who need it (ie selinux users) will rebuild and everyone is happy (selinux users because the program now works and non-selinux users because they did not rebuild for no reason). If i were to randomly revbump packages whenever i needed to add selinux policy deps to packages then i would make 99% of users upset for like no reason. -- Jason
