If you do app-misc/foo:0 in every package and then app-misc/foo _drops_ SLOT 0 and instead introduces SLOT 12.4 and SLOT 15.6, then that won't save you anything. The same if it only renames the current SLOT, without actually introducing another one... in which case you get even more work to do. I'd say: if there is only one SLOT, don't make any assumption about it, unless the SLOT is documented and expected to get additions (as it was for gstreamer, but you can't assume that's the same story for everything else).
