Right. And in this case, code still is law: if the code specifies a version
number field and some miner finds an optimization that only works when the
version number == 1 then it's his own problem once the network upgrades to
version 2. In no way is there anything ethical about blocking the upgrade.

History is not an indicator of the possible values any field can hold in
the future. Limiting your operation to some arbitrary subset is at your own
risk.

Regarding the comparison: I haven't heard anyone even suggest rolling back
the last year of the blockchain to undo the damage already done, any
comparison can end there. If Jonathan wants to persist with this comparison
it would be more like people deciding to stop further funding of the hacked
contract. Yeah, that evil.
