The only minor concern is that the 0.7 chain was restored at 07:30 UTC, which means 6 blocks in the 0.8 orphan fork were mined AFTER the issue should have been resolved if running a standard bitcoind (as far as I'm aware). However, if the decision was made to pay out the orphan chain, it would seem unfair to withhold that compensation on certain blocks in the chain.
Hmm, so by that logic miners should be okay to continue mining on the 0.8 chain now... the line has to be drawn somewhere.
The problems I see with this (and why I think it was a bad idea):
- Miners have no incentive to employ monitoring of the blockchain via multiple clients like Eligius did to avoid mining any blocks on the invalid chain, if they're just going to be reimbursed anyway.
- Gavin can do what he wants with his personal bitcoins, but those funds were donated to the Bitcoin Faucet with the understanding that they would be distributed to new Bitcoin users, not as a bailout for miners.
Edit: That said, what's done is done, and arguing over it isn't going to get anywhere.
