Ah ok, obviously I missed that discussion.

The change set can certainly be converted to two or more packages.
These packages will be hard to maintain, because they overwrite
oodles of system methods, hence I wrote a tool that generates
files like these:

Additionally this change-set modifies the methods that are used
by the compiler to lookup variable bindings. Of course these very
methods are called during file-in. They need to be filed in a particular
order, which is not guarantied by the existing package saving
code. The saved package code needs either manual edits
or the methods need to be split over several dependend packages,
to provide the ordering.

In a nutshell:
The easiest way is certainly to convince Juan to integrate
the change-set into Cuis' core. It only provides hooks
to implement any sort of environment, but does
not change the behavior of the main image.

Now that I come to think about it: A stripped down
version of my Haverize-package would do the job nicely:
The maintenance effort will certainly remain.

Yep can be done!
