Description
In the CSS2-era, pre-@counter-style, you can feature detect whether a given counter style is supported via CSS.supports("list-style-type", "foo") (or similar CSSOM incantations which work further back).
However, with list-style-type now taking <counter-style>, (almost) any <custom-ident> is a valid value for list-style-type, which means you can no longer feature detect what counter styles have built-in support as far as I can tell.
