Thanks Ken. Your comments are stop on.

I just want to add that a comment. We have found that for many newcomers 
to Smalltalk (for example, from Python), the idea of the Smalltalk 
image, and saving it is very alien. Still we want them to be comfortable 
with Smalltalk. On top of that, the idea that "all code is always in the 
repo" helps some team workflows. At least, it worked well for me for 
several team projects, and for maintaining Cuis itself. Hence the 
suggested workflow.

Experienced Smalltalkers like you should choose the workflow that works 
best for them!

Cheers,
