+1 Nothing will ever be marked as known-bad unless it’s in widespread use. Nobody’s ever going to write a die-die-die document for some homebrew cipher or even for a national cipher unless something really spectacular happens. I’d rather not have them marked as “neutral”, which implies they are better than RC4’s “known-bad”. Besides, what about 3DES? For limited amounts of data it works perfectly fine if you follow all the CBC caveats, but with high-speed high-volume connections, you’ll have to rekey often. And there are faster, better alternatives. Do we mark it as “known-bad”? It’s certainly not broken the way RC4 is. I’d rather we not go there.
