For a while, manufacturers were installing inertial 'crash' switches that would turn off the fuel pump. However, there was a tremendous amount of 'false positive' triggering -- many times the number of actual crashes.
This is what my 1996 Ford Explorer has. It only triggered once--during very hard breaking. I didn't know about these switches at the time so I had to have it towed to a shop to find out why it wouldn't start after that.
The switch is easy to reset if you know where it is, so it is decent solution. I still have the Explorer and that is the only time it has triggered. Maybe others were too sensitive.
If you wanted to use the oil pressure sensor to control the fuel pump I suppose you could use a timer to turn on the pump until the oil pressure gets up. As you said, however, complicated.
