It does not support the headers exchange as defined in 0.9.1 either
(0.9.1 is the next version of the protocol that we will support).

Unlikely for 1.6. This is because you are the first person in a very
long time that has asked for this exchange type. We will get around to
it, but there is no ETA. In general, we try to prioritize stuff that
gets asked for a lot, and then of course, when change the schedule to
include stuff for very persuasive people :-)

No they are not - but there is a chance they may appear in the not too
distant future. Again, for the same reason - you're the first to ask
about this - but we actually have draw up some specs for this. As
always, no ETA.
