This is great, but if you had extended the constatnt editor with a pid 
type every extension could have benefited from this.

Again this looks like a feature of general interest.

This really looks like custom code.

I original thought that only trivial encapsulated code would be 
necessary to display custom fields.

I suggest to make the first two options a standard feature of TYPO3 and 
to display the form immediately if no custom fields are necessary. If 
they are then show a big warning that you have to come back to the 
configuration once the extension is installed.
