Hi All! Is it worth adding to the history_stats sensor platform, the ability to track more than one entity state?

examples:

- platform: history_stats
  name: washer_runtime_today
  entity_id: sensor.washing_machine
  state: ['Washing','Rinsing','Spinning']
  type: time
  start: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
  end: '{{ now() }}'

- platform: history_stats
  name: Flights Overhead today
  entity_id: sensor.opensky
  state: ">0"
  type: count
  start: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
  end: '{{ now() }}'
