Who obeys discouraged blocks? I just found this gem - Discouraged Block. It proposes a method where miners "will" (are requested to?) ignore chains with certain blocks at the tip.

It's not like anyone can dictate the behavior of all miners, but if large parts of the network choose this discouragement strategy, then it becomes unprofitable for any single miner not to join in.

Are any current miners/pools for or against this discouragement policy (currently, the only policy is "ignore forks where the coinbase of the block at the tip does not contain the block height")?
I suspect what will happen is that most of the mining pools will use the official client, and so will use the discouragement policy as set by Gavin et al.  This will make it in each pool's best interest to not have their blocks be discouraged.
