The environment variable made sense when we only wanted to give select
access to try the new feature, but I think it's a slippery slope to
allow it to *disable* functionality that, for everyone else, is default.
Once you start having functionality vary across environments, you are
bound to see strange things happen.  E.g., the same code, run with the
same verison of dask, may or may not work depending on a shell setting?
