I'm confused - I already said this. For a fork to work, hard or soft, there
must be support from a majority of the hash power.

Therefore, the usual SPV technique of following the highest work chain
results in ignoring the minority chain produced by the hard fork.

BIP 101 is SPV friendly because the wallets would simply follow the 75%
chain and never even be aware anything has changed. It's backwards
compatible with them in this respect: they already know how to ignore the
no-bigger-blocks fork that'd be created if some miners didn't upgrade
during the grace period.

My point about IsStandard is that miners can and do bypass it, without
expecting that to carry financial consequences or lower the security of
other users. By making it so a block which includes non-standard
transactions can end up being seen as invalid, you are increasing the risk
of accidents that carry financial consequences.

That's incorrect: Miners bypassing IsStandard() risk creating invalid

Gah. You repeated what I just said. Yes, I know miners face that risk, my
point is that they do NOT face such a risk when there's no soft fork in
action and have historically NOT faced that risk at all, hence the
widespread practice of bypassing or modifying this function.

All this approach does is make changing IsStandard() the same as changing
AcceptBlock(), except without the advantage of telling anyone about it.

Obviously. So please enlighten me.

How do ordinary Bitcoin users benefit from this rollout strategy? Put
simply, what is the point of this whole complex soft fork endeavour?
