The efforts that are taking place (too slowly, alas) under the Dexterity
banner are about this, yes. Dexterity will have other aspects too, such
as XML-based and TTW schema building, for those who need/want this.
I see your z3c.form work to pull in the same direction, by the way.

That is indeed my hope.

- reference engine (plone.app.relations gives us most of that, but it
needs to be more immediately usable and have proper widget support)
- inline editing and validation (exists now with formlib, will
probably require a z3c.form compatibility layer too)
- better selection widget (uberselectionwidget needs to be completed)
- file/image widgets, image scaling - maybe z3c.form has this?
- transforms (plone.transforms will probably provide this)
- version-on-edit (needs CMFEditions policy support)
- staging (iterate needs to be generalised away from AT references)
- support for standard metadata edit forms and fieldsets
- field injection ala archetypes.schemaextender
- multi-lingual support (plone.app.multilingual)
- link integrity (plone.app.linkintegrity depends on AT references and
