SCTP was also considered, and in fact the Radiator implementation also offers 
SCTP as an option.
The choice for TCP was a rather pragmatic one. SCTP is available on less 
platforms and the implementations appeared to be a bit more flaky - e.g. the 
SCTP implementation in Linux has had several DoS advisories, and I for one 
wouldn't want to rely on it yet.
Regarding platforms: that LANCOM Access Point implementation wouldn't exist if 
SCTP would have been the transport - to my best knowledge, that feature is 
not even anywhere near their radar.
So, the choice was to concentrate on something that works today and almost 
everywhere.

If I take a look at how Diameter approached this: clients TCP and optional 
SCTP, servers both required: if we were to follow that, we'd still have to 
deal with all the complexities of TCP and add on top of that SCTP. And I'm 
not sure that trying SCTP first and falling back to TCP if that doesn't work 
really fits to the KISS mantra of the IETF.
