Thank you for your detailed explanation.  I realize it is almost

Postscript code.

Don't give up entirely yet, we are still discussing this internally, but I wanted to be realistic in my reply.

  I'm a bit surprised since adjusting the background
color of the generated image to that of emacs still works under gs-9.27.

That's because you are leveraging the BeginPage functionality of PostScript. Its difficult to explain why in detail but as long as the PDF interpreter is written in PostScript that is unlikely to change.

Perhaps it might be a loophole left in gs-9.27 and we possibly have to
be prepared that the future Ghostscript disables this feature as well.

Its possible, I can't deny it, we are always changing the code to fix bugs and add features.
