See https://drafts.csswg.org/css-conditional-5/#at-supports-ext.
Having just updated @font-face
src: format() in bug 1784058 and bug 650372 to follow the current spec, and added the tech() function (bug 1715546), it would be good to also implement the @supports
version of these capability tests.
I have a draft patch that implements this, but have also raised a few minor questions in https://github.com/w3c/csswg-drafts/issues/7633 that I think should be clarified before we actually ship it.

With the @font-face tech() function now behind a nightly-only pref, I suggest we add these functions behind that same pref (as they're so closely related), and then enable them all together once the spec questions are clarified.
