Sounds generally good to me.

I also assumed that the update stream would simply remove carved-out 
packages (with a confirmation prompt).

But Ned's question about that made me think:  Let's say the update 
stream, on the way to 3.4, unloads PWS, Celeste, IRC and Balloon3D.  
Does that mean the official 3.4 release image on squeak.org does not 
include these items?  Or should we provide this as the (very loosely 
termed) "minimal" 3.4 image, and then also provide a "kitchen sink" 3.4 
release which includes these items?

In the case of 3.4, maybe these two releases aren't different enough to 
bother providing both.  But if we only provide the minimal image, some 
people might be confused to see that the 3D demos with Alice & Balloon3D 
are no longer already in the image.

People updating their 3.4alpha image all the way to 3.4 should end up 
with something equivalent to the 3.4 minimal release (assuming they say 
Yes to all the removal confirmations).  I guess this should be fine.

Also, we will probably want some sort of SqueakMap category to indicate 
that the Balloon3D package is "blessed" as part of the kitchen sink 3.4 
release.  (I guess this was brought up earlier.  Perhaps an SM category 
could be "Squeak Central Release" or something like that, to indicate 
that the package was part of the original SqC series of releases.)
