Hmm, here's why:

# python -c 'import pywsman'

it should also answer your "it’s not in the default yum repos" point
you've raised as indeed, both libwsman-devel and openwsman-python
are in "optional" repository with RHEL 6, meaning packages as-are,
without liabilities (mostly enabling the supported ones to be built;
openwsman-python in particular can be just a never triggered byproduct
when the important sibling packages, perhaps build prerequisites,
got built).

So either stick with upstream provided version for binaries + bindings
or you may have better luck with RHEL 7 (slash derivatives).

Anyway, you got me (indirectly) to make this PR against FAs:
