Sounds like a good proposal, however I see a couple of problems that
you don't adress:

- How to manage the code and the changes? Most changes related to
Compiler, CompiledMethod, Behavior, Traits, etc. cannot be loaded
using Monticello.

- What to do with code that is not properly packaged yet? How to pass
code over to another package?

- How to manage fixes that go across multiple packages?

- What to do with essential packages that do not have a maintainer?
Kernel, Collection, ...

- What to do with essential packages that have a maintainer but that
do not get maintained? No insults, therefor no examples ...

Cheers,
Lukas
