Sounds to me like all TCP routes through WAS and TSGW registers itself as a listener so that it can decide whether a packet should go to it or to the next item in the chain (such as HTTP.SYS). Basically what ISAPI priorities did, sorta, in IIS 5/6 but for all TCP, not just IIS.
When you overloading protocols the way TSGW does, you need a way to efficiently decide, without a process switch, where a packet should go. My best guess. Did you ping Christa or Dan?

Having fewer services running with high local system privileges reduces the potential attack surface of the system. WAS also provides process health monitoring and failure recycling for a more robust system. Built-in support of poison queues for receiving messages that cannot be processed makes building fault-tolerant systems easier. And since IIS 7 is also a requirement for TS Gateway: http://technet2.microsoft.com/windowsserver/en/library/edd59c63-a12c-4990-b3 b7-dcf02067deca1033.mspx?mfr=true or http://preview.tinyurl.com/3auvfe Maybe Ken Schaefer can explain this for me.
