What benefit?  The ZTK is a mostly-equivalent subset of the Zope 3.3
shipped with Zope 2.10.x already.  There is nothing "shiny" about using
the ZTK (new features, etc.).

If Plone 3.x can't afford to move the Zope 2.12, then it *definitely*
can't use the ZTK.  Moving the ZTK creates *wildly* more BBB issues /
instability risks than 2.12 ever would.  Constraining the ZTK to fit
this weird pattern you guys have of trying to cherry pick bits of it is
an anti-goal.
