Description Joshua Bell 2015-02-25 23:17:52 UTC 
There are a couple of places where T[] ("pass by reference") is used for constructor arguments:

On interface Path2D:
 Constructor(Path2D[] paths, optional CanvasFillRule fillRule = "nonzero")

On interface WebSocket:
 Constructor(DOMString url, optional (DOMString or DOMString[]) protocols)

In both of these cases, sequence<T> ("pass by value") seems to make more sense, since in neither case does the platform object modify the array.

Is this usage intentional?

This stuff keeps changing and I haven't kept up with what the right answer is. So my plan for the last year or so has been to let WebIDL settle so I can see what comes out on top, then I'll go through and update the spec.
