Update handlers are hard to override - is there a better way of dealing with this?

[neilferreira]

I recently had to create my own 'updateDexterity' method in order to store relations on some additional schema types, I've had to override the @@updateLinkIntegrityInformation view to call my own custom method, rather than the 'modifiedDexterity' as you have hard-coded in the python file.

Would there be a neater way to configure the modifiedDexterity method as the designated update method to manage the updated relations?

Did the same today: used z3c.unconfigure then registered back my own IRetriever.
