[1] That's useful to know, but the problem as I see it is clearly greater than just USE defaults and Portages application of them: Its the complexity that following USE flags implies, in two places: 1. REQUIRED_USE satisfaction 2. DEPEND=" use? ( .... ) !use? ( .... )" interactions across multiple packages. So while it might be *useful* to know you can ignore the defaults in IUSE it doesn't solve the real problem of portage presenting lots of conflicting options to a user which the user may not care about having to solve. So as I see it, this issue is more about asking how we can use IUSE defaults in a way that simplifies end users life, instead of making it harder.
