[Python-modules-team] Bug#910046: python3-grpcio: consider building the Python bindings using the "grpc" source package

[Banpei-kun RX]

Package: python3-grpcio
Version: 1.15.0-1
Severity: normal

The GRPC github project managed by Google
(https://github.com/grpc/grpc) includes support for many languages
including Python. Tarballs generated from that project include support
for all those languages and are linked from the official page at
https://packages.grpc.io/ . This tarball is packaged as the "grpc"
Debian source package, though it hasn't seen a new upload to unstable
in over a year.

The grpcio tarball available from https://pypi.org/project/grpcio/ is
created from the same source, but has the non-Python bits removed (and
includes a few extras, like a copy of zlib/c-ares/openssl).

Two bugs (https://bugs.debian.org/871442 and
https://bugs.debian.org/908873 ) ask for Python support to be enabled
on the grpc source package. I'd guess they were asking for Python 2
bindings, but they might also be interested in the Python 3 bindings
provided by this package.

I'm not aware of any actual problems caused by the current situation,
but packaging the same source twice is unusual.
