I tried to explain this before. See
<http://article.gmane.org/gmane.linux.gentoo.devel/52316/match=use+options>.

Having an ordinary use flag for each library may work well enough when there
are less than three libraries that provide a certain functionality, although
with 2 old-style use flags you already have one bogus fourth option. Default
should not be an option of its own; one of the three options should be the
default.

I'm not trying to hijack this thread. I'm just injecting one message pointing
this out as something I think could benefit from my proposal.

A few real examples may go a long way to explaining something.
