So let's play with the idea of using plone_schemas instead of Archetypes  
for a moment. How does it compare? Off the top of my head, how does it  
support:

  - Creating simple content types baed on schemas

  - Creating folderish types

  - Use of Plone's UI for generated edit forms

  - Ability to make custom views easily

  - DC metadata

  - Ability to use standard CMF actions and aliases, e.g. /edit points to  
edit view, /properties points to metadata edit form etc.

  - Content is automatically indexed in the catalog

  - Things like Modified date are kept up to date automatically

  - Validators on field level and on the whole object level

  - Rename-after-creation (title-to-id generation)

  - Ability to use CMFDynamicViewFTI's IBrowserDefault and  
ISelectableBrowserDefault interfaces, to get the "display" menu, meaning:  
a default view, a list of supplemental views, and ability to set a  
default-page object in the folder (all Plone needs here are the  
interfaces, though these are Z2 style)

  - A way to create custom fields + widgets

Some of these I think I know the answer to, but I'm just curious how far  
along this approach is, and more importantly - where there are gaps, how  
you think they may be closed.
