Is there a reason pooled miners should revert to 0.7 due to the fork?
Miners who use a pool don't necessarily even have bitcoind. They use separate mining software (which does not constitute a node, or build blocks or anything of the sort) and the bitcoins they receive are first credited to the pool eWallet, and can then be withdrawn to any wallet.

The pool is the one choosing the blocks and even if the miner's wallet happens to be bitcoind it has no influence on this process. So there is no reason to downgrade.
