What's the state of the art in shrinking these days?

I'm starting a new web project with Squeak, and I want to create a smallish base image that I can use to build up images for development and deployment. It doesn't have to be absolutely minimal, just unloading unnecessary code and cleaning up the registries, clearing caches etc would fine. 

I tried "Smalltalk shrinkAndCleanDesktop", but it complains about obsolete behaviours still being present, so I guess there's some bit rot there.

Suggestions?
