In fact, this lack of support for ambient depth reduction was one of the
reasons I wanted to have both a --depth and a --new-depth for 'svn update'.
  How surprising it would be for a user who has finally gotten the hang of
using 'svn update --depth' instead of 'svn update --non-recursive' to
upgrade from 1.5 to 1.6 and find that suddenly his shallow updates aren't
just operational scope limitations -- they start throwing away parts of his
working copy!

Implied in my previous paragraph is the timeline in which I expect to see
depth shallowing implemented: post-1.5. And I'm totally cool with that. In
fact, this change makes it much easier to raise a meaningful not-supported
error where such a depth reduction is requested.

PS: I like --set-depth better, too, and will make the change.
