Currently, even if there is no payment extension added to the document, if there is a document value, when you select to send the document via link, there is a notification at the top that says "This document contains a payment $ assigned to ."
This is confusing for clients because, while there is a pricing table on the document, there is no actual payment on the document. It looks like when they send the document, their recipient will be prompted to pay, even though they won't actually be prompted to pay.
