Yes, that does.
I confirmed that priority is set by "1", if I removed
"default_prio_callout" from multipath.conf.

But, it may be better if user can specify null callout explicitly.
Because, for example, user may want to specify that default is 
"pp_balance_units" but no callout is used for specific devices
like following.

---------------------------------------------------------
defaults {
    ...
    default_prio_callout   "/sbin/pp_balance_units %d"
    ...
}
devices {
    device {
        ...
        prio_callout       ""
        ...
    }
}
---------------------------------------------------------
