Personally, I think its a bad idea as we have too many variables in this
field and it could end up with too much namespace pollution. We need to
keep our overrides lean :)

Also, this would automatically make any package machine specific and
make multimachine pointless (anything using COMBINED_FEATURES is machine
specific).
