I am working on an ebuild for the new version of brltty, which includes an api and optional bindings for various languages, one of which is python. I want to use the python use flag to control whether or not those bindings are installed. I have EAPI=1 and IUSE="-python" in the ebuild so that the bindings are not installed unless the user requests them. However, the use_order setting in make.globals does not allow this to work. My make.globals contains: USE_ORDER="env:pkg:conf:defaults:pkginternal:env.d" Shouldn't defaults and pkginternal be swapped so that IUSE defaults will override profile settings?

Swapping them will take some influence away from the profiles and give it to the ebuilds. For example, it will no longer be possible for the profile to enable python globally and be sure that it applies to all ebuilds.
No, defintely not. And while we are at it: I'd like to disallow pkginternal for global use flags in general. Gentoo is loosing consistency at all end, when we allow all and everything per ebuild.
Well, this is a horrible suggestion, sorry, +1 on Comment #2. If the user wants to disable something, they are free to do so, or they are free to switch USE_ORDER on their own. Otherwise the profile defaults should be honored unless you are willing to migrate the *entire* tree from the profile defaults to pkginternal.
Ok, I agree with comment #1. I don't understand why we would need to disallow pkginternal as suggested in comment #2 though based on whether a use flag is local or global since the current stacking order does not allow pkginternal to override use flags that are set in the profiles or by the user.
IUSE defaults were created (and widely accepted) for good reason their design was so that profiles trumped ebuilds
