If you're actively discouraging the solution we do have that works
today, you're not interested in improving it, and you'd like to see some
other solution that doesn't exist yet take its place, then I fear we're
at an impasse and we'll never get anywhere.
As you say, z3c.form (in design principle if nothing else) meets a need
(schema-based forms) that is quite common in Plone. When we did the UI
support for Dexterity, it was the only good alternative we had, since
formlib was both being abandoned by its maintainers and proved too
inflexible and awkward to work with, and hand-written forms would be,
I won't claim that z3c.form is perfect, but I will say that we'd be
better off trying to work with what we have today. It doesn't sound like
you're about to champion a new comprehensive forms solution that will be
usable in the next few weeks or months. :)
I'd also guess that the HTML markup from the default widgets is probably
not as important to everyone else as it seems to be to you.
