That is like replacing passenger trains by freight trains. After all, aren't passengers just one type of freight? SCTP has a whole bunch of features that are of no use to our current applications, that all expect TCP. It would be very unwise to switch to a new transport protocol just because it has one desirable feature that can very easily be built in TCP. Two modules that do 99% the same thing but with different code is bad software design. And SCTP is not backwards compatible with older TCP implementations or access filters or firewalls or anything.
