I personally only care for a return value of the first element picked up by
the mutation macro. So if no elements are picked up by the mutation macro
it's fine to return null. It would make sense for remove to return itself.

If multiple values are passed then you can do one of a view things. Either
return an array of all those values, return null, return the first value or
return the document fragment created by the mutation macro. I don't know
what would be the best thing to do in this case.

That's just me making the example more obvious and verbose.
