Actually, this behavior has flipped back and forth three or four times
(silently!), to the detriment of my @world sets.

The last time I brought it up was in,

  https://bugs.gentoo.org/show_bug.cgi?id=397313

but you can chase the bug trail back to 2004. There are plenty of people
on both sides.

I haven't changed my mind, but the problem is "solved" here. I spend
hours writing metapackages for the things that I want recorded in @world
so that they can be differentiated from the things that were --updated
without --oneshot (which is easy to forget).

The servers that were alive during the silent changes in behavior were
physically retired.
