I see you have already posted the pull request, but the idea makes sense 
to me. In general, making what was previously always output now be 
optional can risk confusing a client that depends on the value being 
present; but since allow-oob has not always been present, and since it 
is still gated by x-oob=on, any sane client using OOB can easily be 
coded to treat an absent indication as not allowing oob for that 
particular command.
