how to handle url's which aren't xarray friendly

This came recently as I was struggling to open a url using xarray. Goes back to https://github.com/pydata/xarray/issues/2233; https://github.com/pydata/xarray/issues/2368

@rsignell-usgs suggested using NetCDF4 https://stackoverflow.com/a/66247797/6046019

Just an FYI. Not sure if it will cause a headache here.

The report names no file, test, or specific behavior to change; begin by reviewing the linked xarray issues and the NetCDF4 suggestion to establish the expected URL handling. A maintainer would need to clarify the affected intake-thredds entry point and define a reproducible URL case and acceptance criteria before work can begin.
