The original intent was to allow for transparent migration:  the end
result has been that Zope2 *uses* selected bits of Zope3, with no intent
 (going forward) that Zope2 will "wither away."  Rather, we are
gradually replacing various bits of Z2, where appropriate, with the Z3
equivalents.

The entire debate here is about whether PAU is really an appropriate
replacement for PAS, given that it doesn't support some use cases out of
the box, and has a smaller set of available plugins.

I wouldn't call the current state obvious. ;)
