We're going to work on fixing it but we can't guarantee it will work long term. We need an open source RCS app and it's not really clear how open RCS is to having alternate implementations. It's hard to see that as simply being openly allowed when Google Messages is mainly failing due to privileged verification checks it wants to do.
