Any new software might introduce problems, and Stackless does some
changes to some type names, which have been a showstopper in
some badly written tests and some bad type checks with "is"
We are going to remove these changes and do pickling with an extension
modules, so that these incompatibilities will vanish, soon.

I think that's up to everybody's taste. Stackless runs stable
enough to be able to replace the standard Python interpreter.
I use it as a full replacement on all machines I have, also
on my Linux server which runs Zope and much other stuff.
I can't see the high risk that you fear. if something breaks,
well, move the old dll back into the place. Where is the
problem? There will soon be an installer, and of course it
will replace the standard interpreter.
