If disconnecting means "unplugging" it from sources/sinks in qjackctl
then no jack application should notice (not even as an error or warning
- it is _not_ an error). In my Planet CCRMA packaged version nothing
happens if I connect or disconnect ports from rakarrack. 

If disconnecting means turning off jack then most applications pop up a
dialog saying that jack is gone. Some are smarter than others and let
you reconnect, on others you have to restart the application. Again, in
the Planet CCRMA version rakarrack pops up a panel saying "try to save
your work" or something to that effect.

Or they just like it that way :-)

I think the color scheme is something to be fixed upstream, right?

My personal take on this is that jack applications should not connect by
themselves to anything unless you tell them to do so. It might be
obvious where to connect to/from in a simple stereo in stereo out
situation, but jack is used many times for multichannel applications. In
those cases the first two output channels and first two input channels
might not go anywhere, or may go to places where you don't want apps
sending stuff by default.
