I believe that backward compatibility is the real driver of this.

I'd be happy to move to using mxDateTime if:

  - We can be 100% backward compatible with people's current 
    expectations (without being just as buggy as a result)

    or

  - If we can't be 100% bw compatible, we could focus on a DateTime
    replacement and migration tools for Zope 3. The new version of 
    DateTime for Zope 3 would then be more free to get rid of old 
    crufty APIs (but we'd be stuck with the current decrepit version
    in the meantime).
