I think Checo's time has passed, at least in a car as aggressively on the edge as that one. But I don't like to think of it as developing the car to suit Max. This is what the engineers would like to do with every car. They want it pointy af, and then they can make it more manageable in setup. It's just that the drivers can't handle it, being human beings with limitations of their own. Hell, they'd probably go further than what Max could handle, too, if they could, but there's no point in going beyond what your #1 driver can handle and maximize in terms of performance. The argument from #2 drivers that they were disadvantaged because the team built the car to suit the lead driver is as old as F1, but they're really just building the fastest car that they can - that their best driver can handle. If there's a wider gap between that team's #1 and #2 drivers, then the #2 suffers more as the car gets more on the edge.
It reminds me of the old coach's saying about athletes: "I'd rather have to dial back an overly aggressive player than have to get a kid to play harder".
