Not quite true, e.g. almost no Elemet is a "connectio object", the one I 
know is "Standard - Text", but even that does not qualify for auto-routing

The three base classes of "connection objects" are "Connection", "OrthConn" 
and "BezierConn". But this does not help much because there currently there 
is no way to get on the base class. And IMO using "dynamic cast" (or 
specific types) to solve the task at hand is the wrong approach anyway.

Yeah, add "Standard - Text" and "Standard - Line" at least ...
