I have the same concern.  I am dubious of tying power grid reliability
to GPS reliability and doubly so in a threat environment which
includes hostile actors.  And if an alternative more reliable timing
standard was used then why use GPS at all?

Inverters lack the overload capability and resistance of rotating iron
unless they are overbuilt in which case they would be uneconomical.
