Have template sensor use icon: instead of icon_template:

Would be really nice, and very much in line with taking out the _template suffix at several places (data_template: and service_template: in scripts ), if we could simply use icon: in the template (binary) sensor configuration https://www.home-assistant.io/integrations/template/ and https://www.home-assistant.io/integrations/binary_sensor.template/

right now, it is not clear we can simply use

icon_template: mdi:toggle-switch

which is, by all means, incorrect, because it isnt a template. Officially we would need to customize the (binary_)sensor with a single icon. Or create fake template:

icon_template: "{{'mdi:toggle-switch'}}"

easiest would be to have the config always use icon:, which accepts both a fixed icon, or a template.

btw, same goes for entity_picture: . we can use

entity_picture_template: /local/afvalwijzer/plastic_saver.png

which of course isnt a template… so why not delete the need for the suffix there too.

please consider?
thanks
