Yes this would be a great enhancement, currently it is being displayed on my dashbaord with 9 decimal places

Explicitly setting a unique_id such as unique_id: sensor.apartment_feels_like_temperature seems to allow HA to work out it should be rounded.

I added it so that I could set the precision on the entity from the UI and after adding it and restarting the entity is only showing default precision (1 decimal place)
