Getting pretty close to default IPv4 route maximum for 6500/7600 routers.

I am wondering if maybe we should make some kind of concerted effort to remind folks about the IPv4 routing table inching closer and closer to the 512K route mark.
We are at about 94/95% right now of 512K.
For most of us, the 512K route mark is arbitrary but for a lot of folks who may still be running 6500/7600 or other routers which are by default configured to crash and burn after 512K routes; it may be a valuable public service.
Even if you don't have this scenario in your network today; chances are you connect to someone who connects to someone who connects to someone (etc...) that does.
In case anyone wants to check on a 6500, you can run: show platform hardware capacity pfc and then look under L3 Forwarding Resources.
Just something to think about before it becomes a story the community talks about for the next decade.
