They should be generic, I think. In particular, I believe `Elements.prototype.selectAll.call(normalArrayOfElements, "selector")` should work, at least assuming `selectAll`s implementation is anything like it is in the Gist. (It may not be, e.g. because it's easier to optimize something that behaves less generically. But the general idea of getting all the elements that match an absolutized version of `selector`, then stuffing them into the object created via `this.constructor`—for whichever `this` you're being called with now—seems sensible.)
