Isn't IDispatch::shutdown already causes all databases to be disconnected?

  In this case the second disconnect attempt should be successful no-op + 
release(), no?..

If you do shutdown before disconnect, I'm not sure the software is
written correctly.

In this case if you do release I think it's going to work.

  How many examples and real life application check status after detach and do 
release on failure?

  Things would be much simpler if release() should be called always.

  No. In this case there is a bug in application that will not be found.
