We disagree.

Just because you don't like all more specifics doesn't mean they are useless.

Not everything is about minimizing FIB size. (And RIB size hasn't been relevant for years.) People pay an ass-ton of 
money to save a few ms off their RTT, if a more specific will allow packets to travel LHR->FRA directly instead of 
packets going from LHR -> SFO -> FRA, they are useful even if there is a covering prefix.

Might be useful if you mentioned what you considered a "smart" way to trim the fib. But then you couldn't bitch and 
moan about people not understanding you, which is the real reason you post to NANOG.
