I would publish an update map without the removed package first.

Then, publish a new version of the Squeak-Version package with a version number increased by the deprecated package's last version number. This is to make our "system version" continuous.

If we want to unload the package automatically, that could be put into the preamble of the Squeak-Version package.

I'm not entirely sure that's generally a good idea though - deprecation usually has a grace period of at least one release cycle (deprecate in on release, remove in next). One distinguishing feature of Squeak is that we try not to break stuff.

In the specific case of Universes I can hardly imagine anyone actively using it, but still. I'm not violently opposed in this case, just cautious.
