Likely a stupid question here

LW's intentions aside, you can use the player sync as you describe it (reveal, GM syncs, Player sync), but it is somewhat cumbersome.

With many VoIP Tools (e.g. Zoom, MS Teams) you can also share your monitor or a window on it. That means you can also employ the Player View during online sessions and the players can see revealed parts of smart maps instantly, even though the PV is somewhat unwieldy by itself.
