Rejected

 * econf --disable-silent-rules (see above)
 * Apply retroactively to EAPI 4?
 * Apply retroactively to all EAPIs? (May be problematic because of additional configure call.)


 * User patches
 * PMS wording, Portage no-op dummy stub
 * Intrusive.
 * Current wording of the spec requires that every ebuild includes a call to the apply_user_patches function in src_prepare. An alternative would be to apply user patches after src_prepare as a default, if the ebuild doesn't call the respective function.
 * The spec doesn't provide any kind of epatch function, so we will end up having two copies of epatch, one for user patches, and the other (from eclass) for ebuilds.
 * Are we happy with the name apply_user_patches? (epatch_user? euserpatch?)


 * License groups in ebuilds
 * A simpler solution would be create separate license files like GPL-2+ for the few cases where this is needed. This would have the advantage that it could be applied to all EAPIs.
