Sounds sorta like the SMTP *BL debate with a new spin.  Data
exist; how one uses them is a matter of preference.

IMHO, landmines would be a very handy way to get a "big picture"
view.  What threshold triggers what activity is up to the user.

I could quickly write a script to find origin ASN of anyone who
pings <machine x>, find all prefixes with that origin ASN, and
blackhole them.  And it would be a pretty stupid manuever, so I
hopefully would know better.

I don't see how landmines are any different... one needn't use
the feed in a predetermined manner.  I think there are more than
a few people who can bang out code, or who know those who can,
hanging out on here.
