Not at all. It's only being installed in specific, high value areas within a specific jurisdiction. And mainly as a backup. Notably by a party which doesn't control GPS (albeit a close ally).

LORAN has also been used near airports in developed areas for a long time.

That isn't the 'base case' though.

The US military initially developed and launched GPS because of the reasons I stated, and it is still widely used as a base case for exactly those reasons.
