In this generality, this is not true at all.  You're confusing
handshakes with protocol layering.  You can do the latter without the
former.  For example, DNS uses UDP without introducing additional
round trips because there is no explicit handshake.  Lack of handshake
generally makes error recovery quite complex once there are multiple
protocol versions you need to support, but handshaking is *not* a
consequence of layering.
