The package requirement system is designed to load packages in a fresh image.

We do not yet have a package migration/update system.  An update system takes the current and (presumably) new package versions, preflights changes to maintain invariants, then updates all live instances as well as updating code.

The upshot is that at this time, required packages are loaded exactly once.

We hope to keep things simple as long as possible.
