Problem

There is a nice, automatically, generated kwargs section. However, it is not clear which values have defaults that are controlled by rcParams, nor what they are.

Suggested improvement

If I understand correctly, this is generated from the documentation of the corresponding set_* methods. An option may be to add a decorator, e.g. @rcparam('axes.facecolor') which adds a third column(?) (Default?) with the contents of :rc:....

(Naturally, not just for Axes.)
