1809 got me thinking in depth about ordinal brushing.
If the order of the ordinal keys do not change, but keys are added or removed due to remove_empty_groups or data streaming, it's possible to change the brush to fit the data.
Since you don't want a redraw to trigger a refilter, this can only work if the dimension uses the natural order of the key, and we use dimension.filterRange (no filterHandler) on the ordinal domain.
That would be a nice simplification. I wonder if I considered this and rejected it when writing the original example.
