I think that this sums up my views on the subject.  Offer/answer is at the
heart of this.  SDP is just the ugly wrapper that attracts all the heat.
SDP isn't so bad if you are doing SAP.  Of course, once you drop O/A, then
you have to build something else.

I made a start at that, but I caution, this approach was soundly rejected:

No matter how right you are, the political reality is that it's not cool to
raise comment 22.
