Comment:
Functionality of `pactl` I miss (not available in `pulsemixer` or `pamixer` afaict):
 - print the default sink: `pactl info  | sed -ne 's/^Default Sink: //p'`
 - print the default source: `pactl info  | sed -ne 's/^Default Source: //p'`
 - set default sink/source: `pactl set-default-{sink,source} ...`
 - list sink-sources: `pactl list short sink-inputs`
 - list source-outputs: `pactl list short source-outputs`
 - move sink-inputs/source-outputs: `pactl move-{sink-input,source-output} ...`


For example: here's a script I use a lot from a hotkey. It cycles the default sink through the available sinks, and also moves all the sink-inputs to the new default sink. Very handy to switch from speakers to headphones, etc.
```
#! /bin/sh

default_sink="$(pactl info | sed -ne 's/^Default Sink: //p')"
sinks="$(pactl list short sinks | awk '{print $2}')"

next="$(printf "%s\n%s\n" "$sinks" "$sinks" | grep -A1 -m1 "$default_sink" | tail -1)"

pactl set-default-sink "$next"

inputs="$(pactl list short sink-inputs | awk '{print $1}')"
for i in $inputs ; do
    pactl move-sink-input $i $next
done
```

In any case, the point is that some of the tools that ship with `pulseaudio` are useful with pipewire, and not obviously replaced (`some scripting` is not good enough, I guess I could replace `pactl` with "some scripting" 
just as much as I could replace this comment with smoke signals).
