FormFu will only support it if someone wants it enough to code it.
This is the 2nd time you've asked about it in as many weeks - so it
looks like you have the most interest in the feature (hint, hint!)

You'd have to look at breaking the validation out, so it could be used
without a form object.
You'd also have to consider how much you want to be auto-generated -
and how practical it is.

I was chatting with bblack (I think) recently, and I think we both
came to the same conclusion that auto-mapping of DB tables/columns to
form fields is only useful for the most basic crud examples, and still
requires configuration of how to handle relationships (especially
regarding updates) that neither of us really wanted to pursue it

A compatibility layer?
I don't recall anyone mentioning such a thing before - so again, I
think it comes down to whether you've got the time... ;)
