This sounds more like a user-interface issue than a problem with runtime-switchable USE flags (GLEP 62). The nice thing about runtime-switchable USE flags is that makes it possible to allow users to unify all of their optional dependency choices in their USE flag settings. You can still implement a --take / --ignore mechanism while allowing the use of runtime-switchable USE conditionals in SDEPEND. It's simply a matter of ignoring the USE conditionals and instead using your --take / --ignore mechanism to select atoms. -- Thanks, Zac
