A naive question: why do we need to get these signals from the grid at all?
Why can't we broadcast a synchronisation message on something like LW radio
that is picked up by every generator large or small?  Then the network
operator can monitor what's happening and adjust the signal as appropriate.

How have we managed to distribute electrical power over huge swaths of land
from multiple independent operators WITHOUT such a mechanism?

 Big steam turbines with lots of spinning inertia and boilers full of
gigajoules of superheated water. And enough 24/7 local generation so
we don't need to import power from France.

Spinning inertia and boilers fulln of super=heated steam are just energy reservoirs. So are grid scale batteries. Getting excited about the former and ignoring the latter is clear evidence of sloppy thinking.

And no commitments to take (or pay for) power that we don't need.

Back in 2008 the book
https://en.wikipedia.org/wiki/Hot,_Flat,_and_Crowded
got published. It advanced the idea that electric car batteries could help stabilise the grid (Tesla Powerwalls are just electric car batteries).
Nobody likes the idea that their assets are being used without their explicit permission, but participants would be paid  for their help.
