Awesome!

I'm reviewing these on the assumption that you've tested they all build.

Are mock and nose required after build-time? If not, they should be
native-inputs.

As for markupsafe, the latest version of the manual has this to say
about propagated-inputs:

Another example where propagated-inputs is useful is for languages that
lack a facility to record the run-time search path akin to ELF’s
RUNPATH; this includes Guile, Python, Perl, GHC, and more. To ensure
that libraries written in those languages can find library code they
depend on at run time, run-time dependencies must be listed in
propagated-inputs rather than inputs. 

I won't mention these potential issues in my reviews of the rest of the
patches.

Setuptools is a native-input.
