Well, depends, doesn't it ?
If you care more about having antique timepieces keeping time
somewhat ok when the grid is stable, it certainly is idiotic.
The bit of the above sentence should notice is "when the grid is
stable", grid stability is getting harder and harder to maintain
and being able to ditch one variable from the equation helps.
The new complications are stuff like:
A city-block blackouts at a load of N kW. X minutes later
power is restored.
It used to be, that you could expect it to come back in at
not more than 1.1*N kW, because all the thermostats would
be clamouring for power.
Today, it comes in at 1.2*N kW, then four seconds later it
jumps to 3.5*N because every laptop and UPS starts charging

Never attribute to malice what can adequately be explained by incompetence.
