Well, actually, this is a regression from HF20. There was a contingency plan in place during HF20 - there was a "kill switch" coded into the hard fork that would have allowed the witnesses to switch back to the old bandwidth system without needing another hardfork or patch. Stinc just asked the witnesses not to use it during the period where the resource credits were stabilizing and no one could transact on the blockchain. Something like that is desperately needed here, but we have gone backwards since HF20 and there is no kill switch coded to reverse the proposed changes if things go south.
