pvpython client fails to connect to the server

It would be greatly helpful, for automating purposes, to add flags when launching pvpython from the shell. For example, I want to launch pvpython in shell which automatically connects to a host, such as in Paraview GUI – going through File > Connect... and clicking on the designated server. Is there something like:

This works

$ paraview -url=cs://localhost:3333

I know this works, because on the server side shell, it says ‘client connected’. But with pvpython, it does not:

pvpython -url=cs://localhost:3333

What might be the problem?

There is an option but it seems non fonctionnal.
