We are more interested in nudging people to contribute open code to benefit everyone.

I doubt there are many functions that are sql encodable in all databases we support. It seems you need something that is specific to your own use case, and also specific to one database: probably the most appropriate path is for you to create and register a new data store factory, which ends up subclassing PostGISDialect and return a different FilterToSQL implementation (likely a subclass of the existing one). Or maybe we could have some plugin (a new SPI) that can add entries to the capabilities document, given a specific database. Jody, any other ideas?
