Yes.  The more interesting question is whether 4.xx is the right group.
We already have 2.31 for “continue”, i.e. a provisional result that asks to go on.
I’m wondering whether that can be used (with the new payload), or whether a 2.xx would be right in general, as we are not trying to tell the client they have made a mistake and the processing of the request is over.
