13 Typically "test" is added to IUSE only when building and/or running the
14 test suite requires specifying additional dependencies. So if we remove
15 "test" from IUSE, we would need to allow DEPEND to have FEATURES-based
16 conditionals. Which would probably mean a new EAPI.
18 I think the easier solution is to modify portage to ignore changes in
19 the "test" USE flag when doing "emerge --newuse".
