I've been trying to discourage use of p2p_oper_{reg_class,channel}
parameters in the configuration file since these were not really ever
designed to be used for normal use cases (i.e., they were only for
initial testing). As such, I'm not sure whether I would really like to
apply this change since it adds more uses for these parameters. The
proper way to force a specific channel is with the freq parameter to the
P2P command that is used to form the group.
