What happens if you reverse polarity on a light fixture?

What happens if you reverse polarity on a light fixture, if you reverse polarity on a light fixture in AC house wiring meaning you connect black hot wire to neutral silver screw and white neutral to hot brass screw, you create reverse polarity at fixture, with light may still turn on and work, but safety is compromised creating shock hazard. What happens is fixture will still light because bulb doesn't care about polarity for incandescent, but socket becomes energized incorrectly, with threaded shell of bulb socket that should be neutral becomes hot, so when you go to change bulb you can get shocked touching metal shell, as shell remains hot even when switch off if switch is on neutral side due to reversal. For screw in fixtures, reverse polarity makes outer threaded part hot instead of neutral, increasing shock risk. For LED fixtures, reverse polarity may cause fixture not to work or damage driver, as some LED fixtures have polarity sensitive electronics. Also safety features like grounding may be compromised. So what happens if you reverse polarity on light fixture, light may still work but creates shock hazard, especially when changing bulb, with threaded shell becoming live, violating electrical code, requiring correction by connecting black hot to brass hot terminal and white neutral to silver neutral terminal, with power off for safety, ensuring fixture is safely wired.
