7 This is excellent progress! Kudos for working on this.

16 Are you sure this is right choice? It seems to me that it'd be better to
17 focus no making things work, and increasing the complexity of the deps
18 makes this harder (and increasing the number of packages you maintain
19 too). Unless you have _abundant_ resources to deal with that, I'd like
20 to discourage you from handling policies that way.
21
22 Furthermore, imagine I'm adding a new package "foo" that is covered by
23 the SELinux policy. Most developers don't use SELinux (hey, I suspect
24 most of them don't even use developer profile; bad, bad!). How do I know
25 whether it's sec-policy/selinux-foo that's not yet added or
26 sec-policy/selinux-games or something else... If the complete policy is
27 in one package, this should be obvious, and we don't even need deps for
28 that.

35 As said by other devs here, I also think it'd be more effective if you
36 just do the change yourself. USE="selinux" doesn't affect anything else
37 so it's safe.
