This sounds like the :read-only and :read-write selectors here are "relied upon" https://www.w3.org/TR/WCAG21/#dfn-relied-upon (when they're not supported, contrast fails). While the normative definition of "accessibility supported" https://www.w3.org/TR/WCAG21/#dfn-accessibility-supported indeed talks about AT and accessibility features in browsers/UAs, I'd say at least in the spirit of that definition I'd also include using/relying on web technologies that have widespread browser support, unless you know for a fact that end users won't actually be using Firefox or IE (e.g. if it's in a closed/controlled environment). A very strict reading of WCAG would, to me, suggest this is not a hard failure of 1.4.3, but in an audit (if discovered) I'd certainly at the very least flag it as a very strong best practice recommendation to fix it.
