I discussed briefly with Tim at the governance summit because we thought about holding off on Remoteform until Form builder was complete. Tim encouraged us to continue because this functionality has not yet been figured out for Form Builder (and might not even be included).
Thanks for the tip! I'll follow up and make some additions to that page.
Also - I've updated the git repo so now, if you are using drush, you can automatically updated the foreign keys only (without having to dump and re-create your database).
