If servers go away / Organisations change, Users and Admins are faced with the old Servername sticking around in the client forever in
a) List of Servers in Crtl-O (File Open Application).
b) List of replicas of Database icons
c) Most likely Bookmarks (I don't really use them)
I am not aware of any obvious way to at least a) (which might be the low hanging fruit - which is to me the most nerve killing one, too.).
