How would this feature be useful?
I need to handle some git commands during sessions, evaluating their output.
Currently it is possible to capture the output of processes executed by run() by setting silent=True.
However, this is not documented.

Describe the solution you'd like
It would be great if capturing output of run() would be made an official documented feature.
It would also be useful to capture output and exit code at the same time.

Describe alternatives you've considered
An alternative would be using subprocess instead of session.run()
