I mean, you can always use more screen. On my touchbar I display the time, battery, weather. I also have a script to start a timer and display the time remaining on it (or the output of any script, really). It saves some screen estate. It's nice! Also there are actions you can program on the touchbar that don't require looking at it. For instance I set it up so that sliding two fingers anywhere on the touchbar changes the volume.
