Hi Chelsea Krause, thanks a lot for your feedback. With the latest update to Survey123 Connect for ArcGIS, your feature service will not be deleted and re-created again unless absolutely necessary. Check this help topic to understand when your feature service will be re-created: Publish your survey—Survey123 for ArcGIS (Beta) | ArcGIS
To download the latest version of Connect, go to this page: Survey123 for ArcGIS | ArcGIS
I double checked and made sure that with this new version (1.4) the sharing of your feature service and Survey will remain untouched when you publish again your Survey. The only exception is when you make changes in your Survey that force the feature service to be re-created. You will get a warning in these cases. Remember to reset the sharing when that happens.
