7 Cycle breaking requires explicit instructions from the ebuilds in
8 question (many of which are system things, which further complicates it)
9 along with support from Portage, so it's a distant future, lot of work
10 thing.

12 Since we need pkg_pretend to cover all the things that aren't use flag
13 related anyway, it makes sense to just go with that rather than
14 delaying things even further. When in the distant future Portage
15 becomes able to deal with cycle breaking, ebuilds can be converted to
16 use something like VALID_USE when they're also updated to export
17 information on which of their flags can safely be toggled.
