using the current integration, it would be nice if the binary_sensors for exceeded_max_bad_sectors and below_min_remaining_life use the device_class: safety.
also, we now have a regular sensor for status per drive, which could also be made into a binary_sensor, and again use the device_class: safety.
it would prevent us to have to use customizations like:
binary_sensor.diskstation_*:
templates:
icon: >
if (state == 'on') return 'mdi:alert-circle';
return 'mdi:check-circle';
for showing correct icons in the frontend.
