[gentoo-user] x11-base/xorg-x11 masked

Hello everyone!
Upon upgrade, portage told me that x11-base/xorg-x11 is masked and will
be removed from the repo on November 1st. I thought "ok, why not do it
now", so I have typed:
	# emerge -W x11-base/xorg-x11
	# emerge -cav
and there was a surprise (not a pleasant one). Since xorg-x11 is a
metapackage it pulled so many things I would like to have still here.
Is there any reasonable way to put all those packages to my world file,
so I can easily remove xorg-x11 without deleting half of my desktop
apps?

Thanks in advance, have a good day!
