Well, I haven't been around all that many years, but I don't recall
a single case in a few WG's I'm participating that an unpresented
work would have been adopted.. sure, it's not written down anywhere, but
sometimes custom is stronger than law...
The OTP WG did nearly all of its work via email, frequently
not holding in-person sessions at IETF meetings because the
mailing list was sufficient. I'm sure there are also other
examples, but that one is handy (I'm the past OTP WG co-chair).
There are too many presentations these days. It isn't required
by IETF rules to present an I-D for it to be seriously considered
by a WG.
