One thing to add is that perhaps in a future version of Bitcoin Core, there could be an option for users to continue using the old consensus rules, or an option to support the new rules (an option when they update and an ability to change in the settings). Both types of user can benefit from the software updates and choose with a single piece of software what they support. Information for whether or not a user is supporting the changes could be included in the version message. Possibly this information could be incorporated into transactions also.
If they wish to support the new rules, then their client would support larger blocks when there is majority miner consensus, otherwise their clients will always only support the old rules. This way the decision is not being forced upon the user in any way. Just an idea.
