Yes.
Don't forget the current promoter is still obliged to do it's job until 2034 or whenever it is, or if they get wound up or bankrupt first. You'd need that before the FIA chat with entrants.
M-Sport have complained for years that they cannot sell the Rally1s that are only allowed in WRC, and say they need to sell cars to be commercial viable. If they aren't interested in selling new cars into a vacuum in all the world's championships - they should just wind up business.
There isn't a boat that's leaving where nobody can build a car in the years after 2027. Everything not being perfect for Monte does not mean a death blow for the series. The combined WRC27/Rally2 class is the back up, not Rally1. This 'limited time' thing is fan's impatience. 2027 will be odd, we already knew it.
