Comment:

 I have a new segregated port ready, providing the latest release. HOWEVER,
 I'm not sure that it's feasible to use it with non-leaf ports like `grpc`,
 as all dependents of the latter should also use it. (And that includes
 non-trivial ports like `py-tensorflow`.)

 So please don't rush to update `grpc` with the new port, until more
 review, analysis, and discussion has occurred, relative to the
 implications.
