I believe there will be demand, being able to transact privately without having to use XMR is use. For example, look at crypto's first big use case: darknet markets. Renvm would have been amazingly valuable for darknet users; previously it's gone something like this:
>buy coins on cuckbase or similar
>if not retarded, attempt to obfuscate coins through a tumbler (and pray you don't get phished, or scammed in the process)
>wait a long ass time cause tumblers were slow and sometimes expensive fees
>move tumbled coins to market to buy fentanyl from china
If renvm could have made that entire process quick, easy, and painless, it would have had a significant amount of use from the darknet alone. And today we have crypto whales, many of whom I'm sure would appreciate being able to transact without having it spammed on twitter, and whose volume should surpass that of the darknet by several orders of magnitude.

Not this is a legit answer although the privacy features could be a long time away. For now they are focusing solely on interoperability
