I agree ... the current behavior is correct.

However, IIRC the NeXTstep workspace had a preferences setting for
'unix expert mode' and when in that mode, you had the option to
'open as directory' so that you could step into a bundle.  It might be 
worth
supporting something similar.  I can't remember if that worked at the
level of the OpenPanel though ... it may have only been a workspace
application menu option.
