The new warning introduced in #16258 is now being triggered by several examples, and the tutorials. At least for the latter, I assume we don't want to go through and just do a blanket Z[:-1, :-1], but instead take a more nuanced approach. Though possibly not; I have not looked at the issues yet, but I don't want to forget about this.

We probably want to change to shading='auto' for these.

Did you track which ones have the warning?
