Granted you'd still have the cruft in your config files, but it would become mostly-harmless cruft, not cruft that caused needless dependencies to get pulled into the dependency tree as a side-effect. And because it would be "only as needed", you could afford to use some of those "only if needed" useflags in a more global manner. For instance, I really don't want to globally define PYTHON_TARGETS to include python2_7, because it will simply install a lot of extra things I know I don't need. But if I could globally define something to the effect of "anything that wants python2.7 support can have it", then that's acceptable globally, because the effect would still turn things on automatically on a per-page level, not at a global level. So you could achieve the same results with much less syntax and much less effort. -- Kent KENTNL - https://metacpan.org/author/KENTNL
