Unless that's forbidden too via the ‘no-other-frame’ parameter ;-)

But the function that created such a frame usually has a handle to it
and can manipulate it like a "normal" frame.  And anyone else can find
out about the frame via ‘frame-list’ or ‘frame-child-frames’ and can
manipulate it like a "normal" frame.

I'd rather leave it to the application or the end user to pick what they
like most than give them some predefined classes to choose from.  This
way they should be able to fine-tune the behavior and appearance of a
separate minibuffer frame, the ediff control panel or the speedbar to
their like.

Next time you encounter such a thing please report it immediately (you
apparently were ahead of Glenn by 15 hours).  Usually, nobody on this
list builds from a clean repository.
