Changing the subject line because it is worth the discussion.

There is absolutely nothing preventing someone from developing a
replacement for Morphic in Squeak. In fact, Squeak provides exactly
the tools needed to support this. The key concept is that we can have
different kinds of Project that can be defined and built up to support
entirely new and different user interface models. Currently we think
mainly of Morphic and MVC, but there is no reason at all that someone
could not build something new and different.

existing MVC and Morphic worlds alive and healthy to support the
new development effort.
About 10 years ago I went through the exercise of trying to bring
a much earlier version Juan's Morphic3 into Squeak.
This project was not successful, but since that time we have made
great progress in cleaning up things like global variable dependencies
in Morphic/MVC, and because of that I think that it would now be
much easier to do this kind of work in today's Squeak.
If anyone has the interest and motivation to try building a new
kind of Morphic, I would say just go ahead and do it. It will not
be simple or easy but if you can build it up step by step, keeping
the existing Morphic/MVC healthy to support your development work,
then I see no reason that it cannot be done.
