As I understand it, trunk would ship about one month after FF ships with 
the same backend. The best estimates of trunk shipping would be first 
quarter 2011.

And that is the main issue. The TB team wants to be free to ship some 
new features before then, and also keep "trunk" working with Mozilla 
2.0  The compromise was to imagine a Tb 3.2 based on Mozilla 1.9.2, but 
not try to maintain all of the trunk work on the 3.2 branch. The plan 
only works if the drivers are fairly conservative as to what gets 
backported to 3.2, as otherwise we end up with the nightmare of trying 
to do development on 2 branches simultaneously. It also only works if 
most of the new features are implemented through extensions, so that 3.2 
really only needs the critical hooks that the extensions need.

It is not a ideal plan, but given the realities it is a good compromise.
