I could.  But frankly I've pretty much had it
with spending time on patches, just to have
them ignored or dismissed summarily.

I'm afraid I'd now have to have some indication
that a patch would be applied, before I'd waste
more time preparing one.

FYI: A patch for what zoom-frm.el offers would
need to include functions `enlarge-font' and
its helper function `frcmds-enlarged-font-name',
both from my library `frame-cmds.el'.  Or just
the alternative version of `enlarge-font' there
(in a comment), which uses `set-face-attribute'.
