I don't think Dave is sabotaging IMPP at the moment. The core documents
are past WGLC and he has not made any further comments on the latest
versions (which were released before Atlanta) which incorporated
amendations to meet his most recent concerns.
I think it would be worth it to try to IETF LC the core IMPP documents at
this time. Dave might find some new grounds for objection, but then again
he might not. Getting those documents out would be beneficial not only to
the APEX situation but also to the SIMPLE situation. It is preferable,
from my perspective, that we hold all the groups to the IMPP model, as
Patrik originally intended.
That much said, I don't strongly object to working around this for the
APEX presence draft. I just hope we don't also have to work around this
for SIMPLE.
