Actually it is like that since the introduction of use-dependencies
like cat/pkg-ver[use] and _before_. Autounmask ist just for the users
convenience to copy paste the needed changes to package.use. I guess
the reason for this coming up more often is that develpopers start to
use use-dependencies more often.

Before the introduction of use dependencies the only possible way was
to stop emerge at build time and tell the user he needs USE="X" for
package Y. With use dependencies it is now possible to inform the user
about it when resolving the dependencies.

So nothing has changed. If a package requires use settings which are
different from the defaults you have to override this on a per package
basis via package.use.
