Translation, this only matters for parameters that change the behaviour
of the master daemon. Removing such a parameter from main.cf did not
result in changed master(8) behaviour without a full restart.
Most users don't modify master(8) parameters other than inet_interfaces,
and changing this without a restart is not supported.
Thus no surprise that there have not been very many problem reports
for this.
By the way, will it be "legal" to do crazy things like change the
"queue_directory" and/or "data_directory" of a running Postfix instance?
