What?
Why not just don't use ediff-defvar-local with defcustoms?
Just write the two extra lines by hand?

AFAICS, it's precisely two variables that seem to be affected:
ediff-use-faces, ediff-highlight-all-diffs

So this email is longer than the change that will be needed.

Pretty sure it's this three-year old change:

rather than something to do with the byte-compiler or defcustom or whatever.
