In our common language a hardfork is a rule difference that can cause
irreconcilable failure in consensus; it's not some political change or
some change in the user's understanding or something fuzzy like that.
Please don't creep the definitions... but arguments over definitions
are silly. If you really object to calling the causes consensus
failure thing something else okay, then suggest a name, but whatever
its called thats what we're talking about here.
Your proposal of having a hardfork but only on the mining nodes has
coordination problems. What happens if we don't know how to contact a
majority of the hashpower to get them to turn off their special
validation code? This is especially a concern because it's not
unlikely that in a few months there may be solo miners with tens of
TH/s... already we have a single party with nearly a majority, though
at the moment they happen to be mining on the largest couple pools.
Far better to have this special code just triggered on a deadline,
which can be widely advertised as "you must upgrade to 0.7.4 or >0.8.1
before this time" and then all switch at once... and then we
demonstrate the viability of a general mechanism that doesn't depend
on poor miner decentralization.
