I think I've expressed my opinion on this option.

I would approve of this approach. I would also approve of leaving an 
informative section of "best practices" within each guideline.

I think it's safe to assume that some L3 items would try to migrate 
upward as we debate them.

I disapprove of these two. In my opinion, the point of the debate is not 
to compress the levels for the sake of compressing them. It's to create 
two reasonable conformance levels authors can choose from, and avoid 
creating an unreasonable level that only causes confusion.

I'm surprised, but intrigued. Did the group determine which/how many 
level 2 SCs would be included?

At first glance, this one looks good, but doesn't solve much. It still 
allows people to overclaim conformance, and it also creates divisions 
among disabilities, which I thought we decided not to do. 
Disability-specific checklists are something that could go into advisory 
or informative text just as successfully.
