Could you please explain what this patch does, specifically why the
no-fallback behavior is needed wherever it was that you added it?  I
assume this has something to do with your background image problem;
please explain in more general terms than "it does what I need it to
do," ie, for either Lispref or Internals (as appropriate).  A patch
would be nice, but if you don't feel like hacking texi, I can do that
part.

It doesn't look like you actually fixed specifier inheritance
behavior; this option was available all along in specifiers
themselves.  Rather you added no-fallback behavior to images or
something that uses images, right?

Did you ever post a patch (besides that auto-commit notice)?  I don't
recall seeing it, and Vin responded to the commit notice....

What was all the whitespace fiddling doing i nthat patch?
