Agreed 100%... I think we all want a fully packagized system, where
every single method in the system belongs to a package. (And
preferably, every method belongs to exactly one package, which means the
Basic configuration of packages has no overrides, if possible.)

Actually, we are in better shape than I originally thought. There were
a dozen or so extra MC packages that showed up after I executed the DoIt
(e.g. "Connectors", "Flexiblevocabularies", "Refactory", etc). However,
when browsing each of these packages, they have no code, they just show
an empty list of *Extensions and nothing else.
So, my guess is that these were perhaps generated by the DoIt from some
extra extension method categories (e.g. "*Connectors") which didn't have
any methods in them. Ah, I see a fresh 3.8-6665-basic image has a
"*flexiblevocabularies-viewer" method category on Object, which the
Reorg cs doesn't do anything with, so that's where they come from...
shouldn't be hard to clean that up.
Well, there is one stray package which did have some code in it after I
ran the DoIt. A package called "UserObjects" has three classes,
CardPlayer55, CardPlayer57, and Player56. Looks like some Etoys
prototype classes which don't need to be there. There are no instances
of these classes in the 6665-basic image, so I could just add an update
cs which deletes them, and deletes the UserObjects class category.

As far as "later changes" go, there are actually only two new updates in
3.8 since your iSqueak Packages image was created, 6663 and 6664. Both
of these updates just change a few existing methods, they don't add or
reorganize anything. So your Reorg changeset looks like it should be
fine as-is, except for the small cleanups I noted above.

Yeah, that sounds like the way to go, then.
I can put up a big warning dialog before this update, telling people
that they should strongly consider just getting a replacement 3.9alpha
image from http://ftp.squeak.org/xxx, noting that proceeding with the
big package-installing update WILL take longer than downloading a
brand-new image. But if they're a glutton for punishment, they can

Hopefully with the big warning message, not too many crazy folks will do
the big package install. :)

Yes, sounds good to me, I wasn't looking forward to "faking" this
I'll see if I can get these new updates added to the 3.9alpha stream
