Hello, just to follow-up on this one, that feature will be included in
https://groups.google.com/a/chromium.org/g/blink-dev/c/n4zf_3FWmAA since
as explained in the original email, MathML is the main use case.

Specification
https://drafts.csswg.org/css-fonts/#font-family-prop
Summary
This generic font family allows authors to style content with a
mathematical font. Main use case is MathML, since this would be the
default font-family on <math> tags.
Blink component
Blink>Fonts
<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink>Fonts>
Motivation
- allow users to select a preference math fonts - allow authors to
style content with a math fonts that has special features for
rendering mathematical expressions (stretchy operators, math glyphs,
etc) - render MathML content with a special math font instead of the
one inherited from the parent.

Risks
Interoperability and Compatibility
- Need to check whether Firefox and WebKit are ok with that.
/Gecko/: No signal
(https://github.com/mozilla/standards-positions/issues/564
<https://chromestatus.com/admin/features/launch/5674318676623360/1?intent=1>)
Firefox has a user preference for the math font used for MathML.
However, it's currently implemented via a fake "math" lang. I sent a
request for position to see if using font-family: math instead would
work better.
/WebKit/: No signal
(https://lists.webkit.org/pipermail/webkit-dev/2021-August/031939.html)
WebKit hardcodes a list of math fonts in the UA sheet. I sent a
request for position to see if using font-family: math instead would
work better.
/Web developers/: Positive Default math font is something that has
historically been important for Firefox/WebKit users. This is
something that was raised in the new MathML WG and had already been
introduced in the CSS spec before, so there seem to be some interest.
Activation
We will likely need to extend the preference/UI, similar to what we
have for other generic names.
Debuggability
font-family already handled by CSS DevTools interface.
