Which is exactly what I was thinking of when I wrote "rarely" and not
"never". It is also the case if you are installing some out of tree
software that has dependencies in the tree, but I prefer to handle that
by creating a set as I can then unmerge the set if I remove the
software, instead of trying to remember wheat I added to world and why.

Because the other slot satisfies the requirements of world, which
contains an unslotted version. But then --update always tries to
installed the newest suitable version. In other words, his system is
broken.
