Here's my question... use.local.desc is already package-specific, so why
would we need yet *another* place to put package-specific definitions?
Would it not be enough to have use.local.desc overlay on use.desc?  If
package foo uses global USE flag bar in a way different from the
description in use.desc, then it should list the USE flag in
use.local.desc with the correct description for that package.
