That would be great, but I have heard nothing of such plans.

I have chosen to use Xen libxenlight, libxenstore and libxenctrl
directly through the 'ctypes' module from my Python 3 applications (I
made some custom wrappers). It is not the most elegant solution and
requires careful updates for any new major Xen version, but works and
can sometimes provide more or better functionality than the Python
modules included with the Xen distribution (they are not very actively
maintained).

Unfortunately, any upstream Xen Python utilities still depend on Python
2, so it may be hard to have a Xen system free of the old Python
interpreter.
