Personally, I'd want a way to turn it off globally for a device or set
of devices. For my internal routers, I see it having value and I too
would welcome the feature. However, for my Internet routers, I see no
reason to have RANCID look at 330,000+ prefixes that constantly change.
Perhaps a "knob" and a "switch" would be in order.

A "knob" idea for minimizing noisiness would be to not output
routes that are newer than a hold-down period and instead
output a single "!Routing change detected" line at the end of
the routes display. If you collect configs hourly, you could
set the hold-down timer to 65 minutes or so.
This way, you would see a single change with the "!Routing
change detected" line in your config history as long as
routes continue to flap between collections. Obviously this
masks multiple routing changes and wouldn't help in
troubleshooting a route flapping problem, but that's not what
RANCID is for anyway.

I like the earlier idea of a "knob" to turn the feature on or
off. It could be particularly "noisy" if you start having
dynamic routing problems.
