Well, the package manager could still treat IUSE_RUNTIME flags as valid
flags for things like USE deps in _other_ packages. So, they don't have
to be entirely independent. The idea is just to limit the scope where
those flags are allowed the package that declares the flags as runtime
flags, so that those runtime flags are only allowed in SRDEPEND.

Part of my concern is not just the implementation details, but also
being able to explain/document for communication purposes. If it's such
a mess that it's difficult to communicate, then it sucks for everyone
involved.
