Sort of no to both actually..

It works because of [1] which means that as long as you are using a profile
that inherit from the base profile (all supported profiles do) you don't need
to add anything to /etc/portage/bashrc.

Functionality wise it is in no way different from putting a case construct like:

case "${CATEGORY}/${PN}" in
    mail-client/evolution | gnome-extra/evolution-data-server )
    CFLAGS="-march=k8 -O1 -ggdb -pipe"
    FEATURES="$FEATURES splitdebug"
    ;;
esac

in /etc/portage/bashrc.

This also means that not all FEATURES set there are going to be respected.
Only the ones that are read in bash code by portage. That does, however,
include splitdebug.
