If we have already started to distinguish the pseudo-elements that don't invalidate the selector list from those that do on a per-prefix basis, maybe it would work the other way round: treat all unknown pseudo-elements as (potentially) valid, _except_ those starting with any prefix _other than_ `-webkit-`?
>From the first glance, this should not break the backwards compatibility, since the most cases of selector-based hacks would be covered with this exception. In the same time, this would allow to add new features in the stylesheets without need to separate things like
```css
.panel:hover, .panel:focus-within { /* styles when the panel is activated by either the mouse or the keyboard */ }
```
into separate rules (as we have to do currently).
