Allow template in min/max for entity_ids

Continuing the discussion from Sensor min/max with group for entities?:

returning to this in the config, it makes me wonder if we could please be able to do anything like this:

  - platform: min_max
    name: Mean indoor temp template
    type: mean
    entity_ids: >
      {{expand('group.indoor_temp_sensors')|map(attribute='entity_id')|list}}

seems so obvious with all current templating possibilities, please consider expanding min.max to use this too?
thanks
