Scipy is a community-driven project, and most often a new feature is
added when someone who needs it or finds it interesting turns up and
implements it.

In this case, both adding the relevant f2py wrappers, and a high-level
rz() function to scipy.linalg seems quite justified. In general, I think
there's no reason to not wrap the whole of LAPACK this way even if there
are no corresponding high-level functions.

Scipy has a workflow for code contributions:

In case you have some code ready but don't want to integrate it in
Scipy, copypaste it to https://gist.github.com and open an issue in
https://github.com/scipy/scipy/issues with a description on what it
does, and a pointer to the Gist. Someone else with too much time on
their hands may later turn up and take a look.
