Yes, I think a realized that a little bit after I sent that message
(after I thought about the meaning of spool_directory).

So would it be possible to have chown called for the directory during
delivery, too? I know now that I can at least change the parent
directory to get correct group permissions for shared email, but I would
think that the expected behavior would be to set the group ownership
based on the group option.
