That's a reasonable rule, though I'd like to make an exception for 
events. All rules like this tend to have their exceptions. :)

Events can come from every which place, and it'd nice to just be able to 
say grok.IObjectModified and not having to worry anymore which 
zope.whatever package that particular event came from. In fact, I'd like 
to add the IBeforeTraverse event to the grok namespace too, as it's 
quite frequently used.

I'm not sure I understand the question, but I define interfaces as a 
form of documentation in most of the (intended-to-be) reusable code I 
write. Also of course whenever you need to define a schema you need to 
use Interface.
