1) Figure out (from the relevant standardization body) if it should be present
2) If so, implement it

The spec doesn't have this attribute. https://www.w3.org/TR/SVG11/fonts.html#FontFaceElement
Comment 3 Myles C. Maxfield 2017-08-10 12:17:34 PDT 
We are the only browser to support SVG fonts in the first place.
Comment 4 Myles C. Maxfield 2017-08-10 12:26:51 PDT 
This should just need to modify Source/WebCore/svg/svgattrs.in and createAttributeNameToCSSPropertyIDMap()
Comment 5 Myles C. Maxfield 2017-08-10 12:27:53 PDT 
Once https://bugs.webkit.org/show_bug.cgi?id=175383 is solved, this can be tested quite easily.
Comment 6 Myles C. Maxfield 2017-10-05 16:32:20 PDT 
Currently, SVGFontFaceElement::parseAttribute() parses according to CSS property grammar, not @font-face descriptor grammar, which means font-display won't work.

I don't think this is worth doing. Supporting <font-face> is only necessary for supporting legacy content, and legacy content doesn't use this new descriptor.
