Yes, sorry about not following this through in time. But here we are.

Sure, but it's a bit annoying to saddle us with some baggage that we never expect to be actually used.
And for that matter, it's no easier to bind a variable around the call than putting a call to `decode-coding-string` around it, is it? We could describe that in NEWS.

The null option is to do nothing and stick to what we have now. It's not a terrible choice either.

Yes, definitely.
