understands the new API, this sysctl can be disabled to achieve full
performance benefits of the new API by disabling the nexthop expansion
and extraneous notifications.
Note that as a backward-compatible mode, dumping of modern features
might be incomplete or wrong. For example, resilient groups will not be
shown as such, but rather as just a list of next hops. Also weights that
do not fit into 8 bits will show incorrectly.
