Hi Neil,
   Yeah, I think that's been true for awhile. However I'm fairly
selective about actually using --depclean when I can use -C, but
that's just me personally. In the case of the OP if I wanted to remove
exactly 1 package then personally I'd just use -C followed by emerge
-pvDuN @world or maybe revdep-rebuild -ip. But again, that's me.
--depclean is probably best for removing lots of things, and as I
think is clear from this thread, I didn't even know that --depclean
followed by a package name was even supported.

Cheers,
Mark
