[racket] rendered documentation in planet archive files

For the PLaneT server to provide viewable documentation, does it rely on 
the uploaded ".plt" archive file to contain a "planet-docs" subdirectory 
containing the rendered documentation?

(I see that "make-planet-archive" will by default render any 
"scribblings" documentation to subdir "planet-docs" in the archive.  I'm 
just checking whether that's currently necessary, before I change my 
stuff to work better with that.)

Thanks,
