Speaking for myself, I'd actively want that behaviour, rather than
just "not mind". When I set up such a special frame, I want Emacs to
leave it alone, and to use another frame for Help buffers and such.
I'm happy for it to pop-up another frame if it needs to, rather than
messing with the existing one.

Indeed, it's a confusing behaviour.
