writing new functions that will verify that stuff works as it should

Yes. See here for example tests for FacetGrid. Testing plotting functions is not trivial but we usually test only very basic functionality. You might find some examples in here.

or that the new addition does not mess up previous plotting behavior?

This is usually covered by continuous integration, which already ran the tests on your current PR (the "all checks have passed" green button above). So on this side you are safe for now, unless our previous tests weren't efficient enough ;-)
