Formidable Forms integration would be useful for piping form submissions to a warehouse.  It's possible to do so now, as Formidable is quite extendable, but it needs to be done for forms individually in most cases.    Especially if the integration was made on a license level, it could run 1000s of sites through a single integration, and leave most of the added work to specific ETL jobs in the case of a logic trap for specific forms.

Formidable support is very developer friendly, and they always take the time to think through every development related request I have had in the past - they are truly thoughtful.  It would stand to reason they'd be open to collaboration.
