I think that the flag needs to be inverted. If we look today, services
are expecting that clients will allow interactive authentication and the
flag is set to zero. So a service would either have to break existing
clients or somehow determine whether they knew about the flag to make a
good choice. If a '1' there was made to be requesting a short reply the
current assumption about zero today would be adequate no mater if the
caller was aware of the new flag or not.

Also, I think we should add at the same time a standard error for "you
wanted quick, but I need interactive." (though it seems errors are only
described in the spec in relation to specific messages, so I'm not sure
where to put it)
