I tried to look up for discussion from the patchwork. These had appeared
in v6. I guess I have to backtrack the discussions from my maidir
because I honestly don't understand why class shutdown would have to
call bus callback explicitly. There's nothing in the commit message
about this nor  is there any comment in the code.

This must be fairly recent development that I've missed?
