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.
