It would be useful if a single diagram element can represent an implicit combination of multiple Ecore objects. 
See for example slides 10 and 11 of https://www.slideshare.net/Obeo_corp/siriuscon2016-integrating-textual-and-graphical-editing-in-the-poosl-ide , where the displayed Sirius Diagram element would ideally be coupled to the combination of an Instance and a Port Ecore object.Unfortunately, the Ecore model does not (always) explicitly contain an EObject for this combination. 
It would be inconvenient to create a derived Ecore attribute, only for this purpose.

After a quick discussion with Pierre-Charles, it seems that what is expected is to keep the same graphical representation when "Port" becomes a "ChannelPort" (in your example). Is it the same feature or another one?

Yes, in our example the user should not observe graphical changes of the port when it gets connected to a channel (and it becomes an channelport)
