The scripts rpyc_classic.py, rpyc_registry.py and rpycd.py which are provided
by upstream are installed under /usr/share/doc/python3-rpyc/bin in Debian. If
there is demand for them to be installed, that can be arranged, but since they
are transitional helpers to ease upgrades from an older version of rpyc than
was even in Debian they didn't seem necessary.
