Only Gecko implements them, nobody else seems interested, and they were dropped from the spec.

Can this wait a bit?

Sure. We should probably get warnings in somewhat soon, though.

Well, actually, assuming we don't want to remove the whole alternate stylesheet selection mechanism, it's not really worth blocking bug 1447009 on it...

"The Document.selectedStylesheetSet and Document.preferredStylesheetSet attributes are removed because they are non-standard and only implemented by Chrome and WebKit" ??

Note the difference in case: selectedStylesheetSet (Chrome/WebKit) vs. selectedStyleSheetSet (Firefox/old spec).

Not getting to this any time soon I think... Someone please grab it if wanted.
