Cool!  Thanks for helping think about this.

I'll do that.  In particular, I propose:

1. The macro extension feature be associated with a new METAL
attribute, extend-macro.  This must be used only in conjunction with
define-macro.

2. The define-macro/use-macro combination will become disallowed once more.

3. The METAL specification must be revised to reflect these changes. 
There are no backward compatibility issues for Zope 3.1.

This needs to be done for Zope 3.1.0c2.

It's attached to issue 440 in the collector:
