Switching from one content type to another should clear fields not usable anymore
When I create a new tt_content entry using the backend of TYPO3 7.6.9 - lets say a text&media entry. I attach/referenace an image to it save it and later on change my mind to switch to a content type header.
The image ist still referenced by the no more visible content, as seen in the ref counter on the FAL object. If I would want to delete the image I get a warning, even if it is no more in real use.
By switching the content type I get a warnin popup about a refresh required, it could be extended to a warning "unused fields will be purged".

I am not sure if you have thought about all side effects:
- This has been the case since day 1 and it is also a great feature as those values could be used later again
- What about editor permissions: So an editor can only change the images but not the title. should then the title be removed?
