URL: https://github.com/apache/beam/pull/12560#issuecomment-685161062


   The issue this is solving is when a `DeferredBase` gets packaged up as part 
of the environment (e.g. in globals, or as an attribute on a PTransform or 
DoFn, etc.) Given how pickling tries to find the transitive closure of 
reachable things, this can happen by accident (and can require contortions to 
avoid), so shouldn't be an error (as long as you don't try to use it). We do 
the same thing for PCollection: 
https://github.com/apache/beam/blob/master/sdks/python/apache_beam/pvalue.py#L170.
