I suspect that as an end-user you do not need to set all three in
most cases.  Just like an unspecified autoupdate can default to
whatever autoinit setting for the submodule is, because it is less
likely that a user wants to have a submodule checked out *and* leave
it stale, an unspecified autoinit can default to the autoclone
setting, because it is less likely that a user who does not want to
have a checkout would want to spend network bandwidth to clone it.
