I tried it (for 3.0) and I find it really beautiful. A really careful test
of the
shrunken image will require some time, but I will do it these days -
as soon as I can find some hours to play with the image.

Yes, that is the price that we have to pay for shrinking. We can
use the  holdForShrink to preserve methods that we do not
want to loose. I find the holdForShrink protocol very beautiful.
(There is a differnt shrink script on the swiki which uses
a method in SystemDictionary to enumerate the names of all
messages that must not be deleted from the image, but the
class-wise holdForShrink is much more convenient to
maintain.)

Yes, the method
    SystemDictionary>>removeAllUnsentMessages
removes the messages with
    Behavior>>removeSelectorSimply:
a method that does not remove the method from the
class organizer.

Attached you find a change set that you should merge with
your file  MajorShrink.cs
It adds code to update the class organization
after shrinking. This removes the names of all removed
methods from the class organizers. This update is also
necessary when you want to do a
condenseSource: Source condensation will fail when
the class organizations are not fully in synch with the
class descriptions.

With that change set I was able to do a
    Smalltalk condenseSources
