There are a couple of great examples of this playing out in "reverse" with some missions that, at pre-F9 launch costs could only afford to be on a rideshare or small launcher and thus were expecting to have to deal with all sorts of limits, only to end up being able to afford a dedicated F9.
There was IXPE, which has been the smallest dedicated payload launched by F9, which otherwise would've had to launch on a much smaller, air-launched pegasus rocket to get to the right inclination. I recall that they were able to simplify some aspects of the satellite deployment due to the roomier vehicle.
There was another mission, maybe Psyche? where the original plan would've required the risk of testing a new kind of engine to get to its deep space destination, but being able to get a dedicated ride instead, that risk was eliminated, such that it was going to be able to get there even if the engine tests failed.
