I worry that this suggestion is going to be derailed by getting over complicated. It should be a simple confirmation option that opens a dialogue to say that some of the value of the time instant will be wasted - do you wish to proceed. Just like the diamond confirmation, there should be an option to disable it. Simple, and very easy for the devs to implement. It won't harm anyone because you would just be able to disable it and things would remain as they were.
