Not only but nearly.
we should even be able to say from which class literal true is and potentially have two different ones.

Yes this is what we want for pharo and this is why we are cleaning everything too .
but for that it means that all the tools chain should be parametrized by environment.
Compiler, senders, implementors, test and refactoring is one of them.
Remote is just one case. And since Nick needs it, this is a way to get momentum.

We are working on it regularly. SystemNavigation was fixed, then we get some problems with TestRunner.
Because we should be able to run tests defined in another one. So this poses the question of late bound classes.
So before getting there we should be able to experiment. And for that we need to have a parametrized environment.

Yes this is the vision. We think about that since a couple of year with marcus.
The bootstrap is also part of the story.
