To be honest, we saved a lot of changes for 2.0 as we knew they would 
be, well, controversial to put in minor releases. Plus there is already 
quite a lot there that is going to require people to test their 
applications anyway.

As long as some guidelines are documented in a "Upgrading to PostGIS 2.0 
from 1.0" section of the documentation, I would think most people 
wouldn't mind as the changes would be mostly mechanical.

I seem to remember at the FOSS4G Code Sprint last year we agreed that as 
long as we work with other projects in the OSGeo community to ensure 
they are prepared for the changes in advance, this shouldn't be an 
issue. And I also seem to remember in the back of mind that you 
volunteered for the liason role... ;)
