It seems like USE would be an unconventional location to store that
information and I'm not sure that it really belongs in the ebuild.
Shoehorning it into package.use might have some benefits but USE
flags are conventionally used to control ebuild behavior rather than
package manager behavior. Perhaps some separate user config file
would be more appropriate for that purpose.
