The proposed interface IComponentRegistry says:

def unregisterSubscriptionAdapter(factory=None, adapts=None,  
provides=None, name=u''):
    """Register a subscriber factory
    ...
    factory
        This is the object used to compute the adapter. The
        factory can be None, in which case any factories
        registered to implement the given provided interface
        for the given required specifications with the given
        name are unregistered.
    """
I thougt the planned component registry implementation covers that use 
case in principle, doesn't it?
