It would be cool if there was some logic which falls back to the backend form xml if there is no frontend one.
But that doesn't necessary have to be in this PR. It can be done later as well I think without breaking anything.
Also for the future it would be nice if the user could override the XML somehow from the template, but that again isn't really in the topic of this PR :smile:
