There is still quite a bit of criteria/parameters missing from RENXT's Constituent List versus what is in RE7. While I know there's already an open idea that was submitted in 2017 pertaining to Addressee/Salutation (which is critical), other fields that are vital for our organization are Gift Subtype (we have an eCommerce store and segment out appeals based on recent gift types) and Total Gift Count (we tailor messaging based on the number of gifts given to our charity).
I'm hoping that any and all fields available in RE7 will also be available in RENXT to export via Constiteunt Lists.
