Probably, since the only reasonable use-case for `:is()` is "all the other selectors were dropped". But we could keep `:is()` working, if needed for compat.
> Isn't it also easier to serialize all selectors as is?
Not really, because then you need to preserve the specified string. Also it would be a pretty big behavior change (e.g. `.foo /* whatever */ .bar` would serialize as-is rather than with whitespace normalized and comments removed.
