None of that seems very likely. Did you just copy/paste it? :)

Oh, so you're adding another one ... I guess I understand better now.

some of this refactoring might better be in a separate patch.

ditto - too big for here.

That doesn't seem reasonable really - if you're reporting out of band
then don't report it as TX status but rather with the eosp() call.
