User Access to Complex Data Types and Custom Enrichments in Clay

Are there any plans to give users access to lists, objects, and more complex primitives/building blocks? At the moment, everything needs to be normalised to text/String, so I have to use lots of JSON.parse and JSON.stringify calls to manipulate the data between enrichments. As tables become complex, it would be great to be able to use lists and objects natively (like you can for 1st party enrichments). It would also be super helpful to be able to build more complex custom enrichments. In particular when they involve callbacks. The workaround I use is creating another table that catches the callback and then writes the results to the primary table. But this is a bit of a pain to manage and adds complexity. It would be simpler if the column that originates the call could receive the callback as it does for some of the 1st party enrichments. Basically, will end users ever have access to similar tools as 1st party Clay developers? I understand this is only useful for (technical) power users, so I completely understand if this is not a priority.
