Well, we kind've do. I just don't advertise it. The SqueakTrunk build
on CI takes a hand-crafted "core" image, updates it and runs all its
tests. Noone notices that Nebraska, Universes and XML-Parser are no
longer in the Core because a second CI job, ReleaseSqueakTrunk, loads
these in.

My aim is to progressively rip more and more out of the hand-crafted
base image, and keep loading those unloaded packages in the
ReleaseSqueakTrunk. I also add the unloaded packages as test suites in
the ExternalPackages job.

Chris Muller has rightly raised concern that this core+extra image
isn't itself tested. I think the answer to this is that (a) we often
have no idea whether some package works currently because there are
far too few tests, but (b) we can always run the full set of core
tests + package tests on (a copy of) the resulting core+extra image.

But right now it's extremely hard to unload packages because so many
packages have circular dependencies and the like. Most of my work
recently has been around cutting the easier parts of the tangle, and
raising the profile of some of the less easy parts.
