I really like the data field type "raw", because it allows users to use includes and modules in the data field (as they can already do when not using data forms).

Data forms are have made organizing pages a breeze, with inbuilt user input validation techniques and general UI for wikis. Retaining the raw field type as it is means we have the best of both worlds: normal pages and organized ones.

My wish is that the “experimental” raw type becomes a permanent feature that we can rely on.
