> Batteries are traditionally grid-following, so they'll just follow whatever frequency the grid is already running on.

Is there in theory an amount of batteries with inverters where enough energy is created to "not notice" the spinning generators going away? I.e. everyone is trying to follow the frequency that's already flowing therefore everyone sees some frequency flowing? Or would it be like talking with echo/delay where they start slowing down by always being behind until everyone stops?
