I can confirm that this bug is still present in Emacs 27, but it's weird
that this hasn't come up more often.  I mean, defsubsts are commonly
used, and not having byte compilation warnings about the wrong number of
arguments is something you'd expect to come up more often.

Nope.

I tried briefly to follow the logic in the stuff that'd give a "attempt
to open-code", but it doesn't seem to be triggered at all in this case.
