Yes, sorrowly. But the discussion was focussed around another layer
above wxPython, Tkinter etc. to make those toolkits more pythonic. Ed
promised to support many GUI toolkits as backend in future ( reviving
the failed AnyGUI approach ). That's o.k. as long as tedious
maintenance is a fun job for some people and they do it right. I don't
say that Ed produces crap, but I'll be carefull and wait a couple of
years before using such kind of stuff in production code.

It makes all difference in practice. A few levels of stacking does not
hurt in theory because it is easy to abstract them away by perfect
machinery.

As long as the chain of layers does not break and the conveyor-belt
rolls efficiently it's like living in theory ;)
