I think he/she is not talking about the transport protocol (TCP/UDP), but the higher up layers (5 - 7) cramming functionality from the lower layers. Might be reading it the wrong way.

They only try to cram functionality from lower levels into higher ones because establishing new lower ones is nearly impossible. SCTP (or variants of it) would implement a lot that is now build on higher levels, but there is a reason it's only used in private networks.

No kidding, take a look at the presentation[0] for multipath TCP - and that was a relatively 'simple' transport layer modification. Look at slide #30 for a glimpse into the madness caused by crappy middleboxes.

The alternative is to layer something over HTTP. That's may be even worse. There are no simple ways to upgrade global infrastructure.
