ZHA entities are gone right?

I wanted to make sure of something while I clean up. ZHA entities are gone right? So you get your entities for your light, sensor, etc… also the new battery entity, but in the latest release it added all your old entities to “unused” so I want to clean up… I have tons of old ZHA, from 2-3 previous zha changes, wanted to make sure I can delete all ZHA entities that say:

“This entity is currently unavailable and is an orphan to a removed, changed or dysfunctional integration or device.
If the entity is no longer in use, you can clean it up by removing it.”

This is me just finally cleaning up, here is the PR back in July to remove zha entities…
