People were always talking about this, dont know why it was never proposed earlier as a BIP. But its very difficult now for any BIP proposal to get accepted regardless of if majority want it because miners will never vote for anything other than BIP 100 now its been suggested.
Unless you take a different approach and fork based on 90% or so of node majority rather than using hash majority, but you wouldn't want to do that without first confirming there was already a very strong consensus within the economy for the BIP.
