With ArcGIS Pro 2.6 ESRI has included the XARRAY Package as a default package in ArcGIS Pro. This is a great inclusion with it allowing power analysis of Netcdf data. One Caveat however is that XARRAY depends on the DASK package as well and that is not included in the Default Python Env. Could DASK be included in future updates/releases in the future?
dask isn't on the "required" list
Installation — xarray 0.16.2.dev3+g18a59a6d.d20200920 documentation
but it can be installed separately, however, its dependency list is a bit longish and there may be license restrictions if esri included it in their distribution, which wouldn' limit you installing it yourself

Dask is not required, but if one tries to work with a netcdf data of any larger size it will ask you to use Dask. I know that once can clone the default environment and install Dask. But if a developer is trying to develop tools and training that use netcdf it would be best not to have to clone and install Dask.
