the tilt is a safety issue... shuts off FI, just like a FI car if in an accident. And its a good idea. But if it corrodes and the bike won't start, its a pain. I've only dealt with 1 with that issue.
As for oil starvation. .... it can be a real issue if you don't know. For example does your X have the oil pick up tube inside the primary? It is an aftermarket tube, that was developed by the vendors, so that the owners can warm their bikes up on the kick stand. Early on it was proven that the X's would cavitate the oil, and actually suck air on the kickstand during warm up. Proven with a manual oil pressure gauge mounted in the oil pressure sending unit hole. There's a very old video that was made in the early days, that shows this demostration. The manual gauge was bobbing the needle a lot. ...
So if you were to bypass or remove the tilt switch, and dump the bike... like most bikes, I'd say yeah, it probably wouldn't do it any good if it stayed running...
But hey.... who wants to dump an X... I mean really..... hee hee hee....
