That PR looks OK to me. For the issue I raised, maybe:
This document specifically removes support for displaying math in Unicode or as
dedicated SVG figures ...
This leaves the door open for SVG figures that incidentally contain math. Such
figures might be problematic for accessibility, but that's a more general
concern with figures anyway.

Hi,
The draft says:
"Mathematical notation in RFCs will no longer be accepted in Unicode or
Scalable Vector Graphics (SVGs) for RFCXML or the HTML publication
format."
I think that has to be qualified. It could happen that a diagram
contains a fragment of math notation, for example in the label of the
axis of a graph, and we don't want to accidentally forbid that.

Hello,
We'd like to allow better mathematical notation in RFCs, so Martin, Lars and I
put together this policy draft:
https://datatracker.ietf.org/doc/html/draft-rossi-mathinrfcs
<https://datatracker.ietf.org/doc/html/draft-rossi-mathinrfcs>
The language is very similar to the SVG doc that just made it through AUTH48
[1].
Please let us know what you think.

Abstract:
This document defines policy and allows new technology for the
representation of mathematical notation in RFCXML and relevant
publication formats. After implementation of this policy,
mathematical notation in RFCXML and the HTML publication format will
no longer be accepted in Unicode or Scalable Vector Graphics (SVGs).
