Technically, this is breaking because it removes write access, i.e. replacing the whole dict, without prior warning.
But I think I'm ok with that. It should be very rare. https://github.com/search?q=%2FMaxNLocator%5C.default_params%2F+language%3APython+NOT+is%3Afork&type=code does not yield any such cases. If people overwrite defaults, they tend to do it on a per-element basis.

Do we need the check for None here? The parameter is documented as only taking an integer or "auto", and it already defaults to 10.

Indeed, I think we don't need to. Fixed.
Directly set the defaults of MaxNLocator in the constructor signature (with a cutout for `nbins=None`), rather than in a separate variable. Support passing kwargs to AutoLocator as well (they're already supported by MaxNLocator).
