I think I was one of the people at the meeting who argued against it, so I'll 
talk turkey:

INFO is in wide use today, and it works(!), with barely any interop problems.

IMHO, the requirements driving the INFO packages draft was to solve two 
specific problems with current INFO:
1) Negotiation/advertisement of INFO uses, so that a UA is not "surprised" when 
it gets an INFO, and we don't need system configuration for every UA we talk to 
for what it can do.  Configuration on a system-wide basis is one thing, but 
configuration per far-end is *really* bad.
2) Indication of what the use is for the INFO message that is sent, so that one 
can receive the INFO method without ambiguity as to its purpose.

Those are the only things that drove a new draft, AFAIK.  Anything else is 
basically gravy.

We also had consensus (I think) a while back that the only chance we have to 
make people use this draft instead of current INFO was to:
a) Keep it simple.
b) Keep it simple.
c) Keep it simple.

So ISTM we don't have room for gravy - we need to focus on slice of the pie 
that we care about.  We need to keep the weight off the draft by sticking to 
the meat of the problems being solved, without stuffing in extra capabilities 
and by skipping the extra portions.  If we pile on more features, and mash in 
scenarios not covered by current INFO, there's little chance current 
systems/implementers will digest this thing and we'll end up with a dead duck 
instead.  So I was one of the people that cried fowl at the last meeting, and 
suggested we scrape the extras off our plate so we can serve up a draft people 
can really swallow.  Otherwise they'll continue doing what they're doing now.  
We can shop around for more features the day after the draft is done, by 
putting extras in packages - but having people buy into those is only possible 
if we make the base draft cheap to implement now.
