python-webob 1.1 vs 1.2

Guys, I noticed that we started building Webob 1.1 in F17. However, I had some issues with 1.1, namely they deprecated a bunch of attributes by throwing warnings. This causes unit tests to fail and ironically the way 1.2 completely disables them with None is much easier to detect, so that code supporting both 1.0 and 1.2 may be written. Code supporting 1.0 and 1.1 is much more difficult. So, do you think we could just jump over 1.1 and go to 1.2 betas instead? Alternatively, I'd love some advice on how to deal with 1.1. -- Pete
