Similar opinion as Eli.  I don't feel that sorting is a basic sequence
operation.  Unlike concatenation, you don't sort streams (lazy lists)
for example.

It's a corner case like `seq-sort' I don't have a strong opinion about.
I think I would prefer having the function defined somewhere else and,
maybe, use it in the list implementation of a `seq-sort-on' if we really
want it.

But do you really think people often would "sort-on" anything but lists?
