Then you have to drag the context around all the time. You might not have been 
around when we still had to use ContextWrappers for parent information, but 
it was just a nightmare. This might be on a smaller scale, but it is the same 
issue. Having to manually carry something like contextual information around 
is tedious, unnecessary and a source for unexplainable bugs.

We want to get rid of binding, since not every user of zope.interface and 
zope.schema will want to do the same with interfaces and schemas that we do. 
So they are something zope.app specific; therefore the adapter.
