For context: we didn't explicitly implement a .get() method on Dataset, we get it implemented for free because xarray.Dataset inherits from collections.abc.Mapping. So the only practical difference between .get() and [] on Dataset is the same as the difference for a general Python mapping: .get() returns a default value (which defaults to None) instead of raising KeyError.

I'm not sure it's particularly useful to show examples using .get() here, unless we want to show this difference in behavior if a key is not found.
