Math Notation in Gemini?

[Oliver Simmons]

One of the golden rules of Gemini is user control, and by *default*
this would be off.
MathML/similar via preformatted blocks would be fine IMO, *if the user
enabled it*.

I don't see anyone ever making clients that render HTML as, well, why
would they?
But I understand that concern.

The spec never explicitly disallows this, but it does say how
preformatted lines should be displayed, which ~kinda disallows it.

IMO this specific case of MathML/similar would be perfectly fine.
