Seems pipx is neither quiet nor json/scriptable?

Description

I must be missing something … but how do I use pipx in a cronjob or shell script? This won't suppress output and still prints progress info:

pipx upgrade-all >/dev/null

And while pipx install --pip-args could be used to pass --quiet, this won't work for upgrade-all. Additionally, there is only a --json option for pipx list --json, right? What if I want to work with (json/no) pipx output with all subcommands? Wouldn't it be good to introduce --quiet and make --json and --quiet an option that changes the behaviour of pipx?

Research direction
Examine the existing CLI argument parser (likely using argparse) to see how json is implemented for the 'list' subcommand. Then extend the same pattern to other subcommands such as 'upgrade all' by adding a quiet flag. Also consider adding json to all subcommands that output text. Look at the pipx source code, specifically the cli module, to understand the command structure.
