Yes, got that - issue 5689. Also of interest is issue 5411 - adding .xz
support to distutils. But I think that these are separate projects that
should wait until the lzma module is finalized.

Indeed, PEP 399 specifically notes that exemptions can be granted for
modules that wrap external C libraries.

I'm not too sure about that - PEP 399 explicitly says that using ctypes is
frowned upon, and doesn't mention anywhere that it should be used in this
sort of situation.
