I could force this in the eclass with the following flow if I know how
to tell if the ebuild inheriting it is in the main tree or not:

# in_main_tree is a place holder for a test to see if the ebuld running
# this is in the tree
	if [[ -n ${EGO_SUM} && in_main_tree ]]; then
		eqawarn "EGO_SUM is not allowed in the main tree"
		eqawarn "This will become a fatal error in the future"
	fi

	The only question is, is there a way to reliably tell whether or not
	we are  in the main tree?
