When it was originally added, it was supposed to handle all of the
pre-parsing of the selector to prepend :scope to each selector in the
group, including handling things like ">div, +p". But it got watered
down a lot since then due to complaints from the CSSWG about modifying
the selector syntax, and now it can only handle implying :scope and a
descendant combinator.
Admittedly, that does lower its value significantly and I may end up
just dropping it. The only benefit it has now is that it's mildly more
intuitive for authors, since unlike the existing non-scoped method, it
can return siblings of the context node.
e.g.
elm.queryScopedSelectorAll(":scope+p");
But, in most cases, except where elm is in a disconnected tree, that is
really equivalent to:
document.querySelectorAll(":scope+p", elm);
Anyway, since the CfC for FPWD has already begun, I'd rather not make
any major changes till afterwards. I'd also like to hear from a few
other people on this issue.
