which IMHO is ok. The extension that uses a hook could/should just set 
it's compatibility with TYPO3 to the known-to-be-working versions.

If the interface then chages, the developer needs to adjust his 
extension and can then raise the compatibility version.

This has advantages for both users and developers:
* developer do (should) not get inquiries about not working versions - 
it's declared to be not compatible already
* the user also knows that it's not going to work
