Can you change _gca to take an optional dictionary? So like

def _gca(rc=None):
    with plt.rc_context(rc):
        return plt.gca()

that way, we aren't limited to just figsize when we call gca. You'd call it like ax = _gca({'figure.figsize': figsize})

I can do that. Note that I can't unconditionally overwrite figure.figsize, because if it's not specified, it's None, and that would overwrite the default in rcParams. That's why I have it pass in an empty dict when it's None. Anyway, I can push that one level up the call stack like you mention.

Ah that's unfortunate. Still probably best to handle it outside.

return plt.gca()
# No way of passing in figsize via gca() call so temporarily change the
# defaults so that when it calls figure() it uses our figsize.
rc = {'figure.figsize': figsize} if figsize is not None else {}
