Not for now, but it makes sense, though for example with UCSI we don't receive any notification in case of Attention, so this is something that is not going to be always available. I'm going to be away next week, but I'm planning to prepare v2 of these patches after that. I'll also propose something for handling Attention Command and polling then.
