Yes when you index out a single location z becomes a scalar (similar with numpy). if you want to keep the dimension use .sel(z=['0']).

I expect that a singleton coordinate of a dataset not to be a coordinate of other coordinates present in the dataset

Xarray only checks if a coordinate variable's dimensions are a subset of the extracted DataArray dimensions. for a scalar, .dims is an empty set, and an empty set is a subset of every set.
