I've tried doing this with an actual bug, namely bug #22983 "syntax-ppss
returns wrong result".  That was over three months ago, and still there
is no fix.  You don't appear to want to take any responsibility for
getting it fixed, even though it's in "your" code.

I've no expectation anything would be done about more abstract design
flaws reported as bugs.

What I dislike about these things, as you well know, are the failings in
their fundamental design and the restrictions these place upon other
software, the way things were implemented before being thought through
properly.  So we have bug #22983, and we have the ghastly abortion of
low level code in syntax.c calling out to high level lisp code "just to
make sure things are propertized properly".

If that was the sort of thing I was unhappy with, I'd have little indeed
to be unhappy about.
