LyX uses the offending commands directly (see below), so we have to do
something.

It is fine. Even without the new luatex, I see that the offending part is
the use of:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
\pdfpageheight\paperheight
\pdfpagewidth\paperwidth
in case a non-standard paper size is set.
IMO, LyX should write
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
\IfFileExists{luatex85.sty}{\usepackage{luatex85}}{}
\pdfpageheight\paperheight
\pdfpagewidth\paperwidth
if exporting to LuaTeX and \pdfpage* commands are required.
(With a comment in the code to change this to the new syntax next year or
so...)
