In general, I dislike frames. Right now, I'm using
(setq ediff-window-setup-function #'ediff-setup-windows-plain)
To ensure that ediff does not create a frame when it starts.
However, certain commands, like ediff-show-registry still open up new frames.
Is there any way I can completely disable the creation of frames in ediff?
There is an internal predicate in ediff-init.el, called ediff-window-display-p. When I redefined it (after loading ediff, of course) like so, everything works in a single frame, including the function you mentioned as a problem:
(defun ediff-window-display-p () nil)
I do agree with @lawlist that this is a nice feature request -- to fix ediff-window-setup-function.
(advice-add 'ediff-window-display-p :override #'ignore), which can more easily be reversed with advice-remove (plus it doesn't require loading ediff first).

ediff-setup-windows-plain takes over the whole frame -- I want to keep my "context" windows open (eg notes and other files). So I wrote a custom window setup function (uses custom display-buffer powered by ace-window to choose where to maybe split windows and display new buffers). It seems that when Ediff boots up it checks this ediff-window-display-p and if false, bypasses the custom window setup function and uses ediff-setup-windows-plain. So for my custom setup, I'll either avoid ediff-show-registry, or write custom command.

ediff-skip-unsuitable-frames, or commenting that out entirely withinediff-show-registry-- e.g., comment out:(ediff-skip-unsuitable-frames 'ok-unsplittable)? – lawlist Oct 2 '15 at 3:43ediff-family of libraries for(make-frameand you'll find a few places that need fixing to suit your preferences. Your request is certainly reasonable, and would merit (in my opinion) a feature request to the author and/or Emacs team -- most people will assumeediff-setup-windows-plainshould apply across the board without the variousmake-frameexceptions. – lawlist Oct 2 '15 at 3:49
