That's all fine and dandy but in the Real world, hardly of any use. Only a handful of lenses actually can resolve the details of a 36mp sensor. Forget about a 50mp sensor on that Sony glass.
That's not how resolution works. The final value is a result of the combination of all components (lens and sensor or film) and is always lower than the weakest component. But strengthening any component leads to an increase for the entire system, even if that specific component is "past" the resolution of the weakest component, i.e. the weakest component is not a hard limit in the way you're imagining it to be.
At any rate, you can discern plenty of lenses on 24 MP APS-C sensors which means they will show an advantage on 50 MP FF.
That said, it would be difficult to see any difference between 24/36/50 MP except on the very largest prints. We're hitting the point of diminishing returns with respect to even 36" prints.
You said it is always lower than the weakest component. So therefore, the weakest component has to be a hard limit on resolution. Perhaps increasing the resolution of another component causes the system resolution to asymptotically approach the weakest components resolution?
