It is if you have only volunteers to maintain the code base, and the
changes significantly increase maintenance complexity. Also, a significant
number of third-party C extensions would need to be modified for
compatibility, as has already been pointed out.
Note also that Jython and IronPython exist, and run on VMs that address
these issues, and that the PyPy project can generate code for many kinds of
backends. There's nothting stopping anybody from creating a
multiprocessor-friendly backend for PyPy, for example.
