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.
