US grid to float high in freq:
Regulatory bods to let grid drift generally higher in freq to improve stability and reliability, conditioned on the assumption nobody cares about grid-based time:

During peak demand the US grid would always run a bit slow, by fractions of a percent, and then run high at night to compensate. My high school had these massive IBM clocks in the hallways, looming darkly from the ceiling. One outside every classroom and all running running in inhuman lockstep. Awful "bang" every minute when the hands would move. Imagining you were in some sort of penal or mental facility was not difficult. I think they were on grid freq and could swear during some classes that freq was actually tens of percent low.
