Technically it could, but the issue here would be what you are going
to do with a has_version check on an IUSE_RUNTIME dep -- the package
should do filesystem-identical installs no matter what status of
IUSE_RUNTIME flags, so whatever one would do with a has_version check
would have to not change any part of the build or installation.

I could see it being of use within pkg_configure(), though; ie, emerge
- --config pkg should then be able to reliably set up default configs
based on the runtime installs.   However, that's the only place I can
picture it being viable.
