The current focus for the 1511 enhancement is just a analytics usecase to create dashboards, kpis, trends, averages etcs of the survey results.
When you need to use the survey results to drive process/workflow such as create/update other objects or write back to the ticket with survey results into ticket fields, then your solution is the only way to achieve those requirements.
So I can easily see both solutions complementing survey data requirements quite nicely.
