Occasionally people put a setting like USE="${USE} foo" a the top of make.defaults, and that pulls USE from the parent profile into the current profile, which can cause unexpected override of parent profile package.use. We can guard against this if we remove the parent profile's USE setting from the expand_map variable.
Patch posted for review: https://archives.gentoo.org/gentoo-portage-dev/message/10b2115ed7f1c42f36ec45108a5f4e20 https://github.com/gentoo/portage/pull/670
It would be nice to guard the USE_EXPAND variables like this too, but USE_EXPAND is not known until after make.defaults is evaluated.

This prevents accidents triggered by USE="${USE} ..." settings at the top of make.defaults which caused parent profile USE to override parent profile package.use settings. Note that would be nice to guard the USE_EXPAND variables like this too, but unfortunately USE_EXPAND is not known until after make.defaults has been evaluated, so that will require some form of make.defaults preprocessing.
