Thanks! Good point!

Because if I decide to keep it, all dependencies it pulls-in don't get
updated until the top-level package starts depending on a different
version of those packages. Actually this is the main reason I started
this practice.
"emerge --depclean" yells a big warning that it is broken.

No, no! I'm saying just the opposite - the more packages you have
recorded in the world list, the slower scanning you get.
