Yes, that's right, also increasing the total bandwidth (for adaptive traffic) is a use case.

If you have multiple flows and multiple interfaces, it's rather easy to simply route/schedule different flows over different links (a la ECMP). The problem comes up if you have a service with one flow that needs more capacity than a single link can provide. The example we’ve been working on is HD video streaming in rural areas where the DSL is limited but LTE is provided and sparely used. In this case you need re-oder buffers and additional signaling between the tunnel endpoints.

I think I would say, though, that this is useful when a single flow needs _or can benefit from_ more bandwidth than a single link provides, because a solution is also desirable in this area to allow, for example, content downloads to finish more quickly, even if they do not _need_ to finish more quickly in order to be useful.  Does that make sense?
