This is unfortunately so well-trodden that this text was added without consideration for people who weren't involved in the trampling process. I think that "strongly" can be struck here, it's working too hard. And smart people will latch onto it. Context: When we use DATAGRAMs in HTTP (and likely in other contexts) there will be a need to bind each DATAGRAM to a (request) stream. That's necessary to ensure that flows of DATAGRAMs can be routed by gateways and the like along with the stream. There were lots of debates about how to manage that binding and the layer at which it would be documented. This text is likely intended to record the conclusion that this document definitely isn't where that sort of binding occurs, but for someone without that history. It doesn't really achieve that though and because it doesn't need to (why would you think that any association exists?), it ends up being distracting.
