I use the fork lock in a strange area when I will be away from the bike for a while. For example, Oatman. I only park in neutral on level ground and where I feel the bike is secure.
I thought I was real good about never walking away from the bike without the key, but I left the ignition on last week at my office. Just too many distractions right then. Bike would not start of course, just clicking. I put it in gear, got coasting and eased the clutch out. Started right up. Then I had to reset the clock. Maybe that is why bikes don't have automatic transmissions.
If I park in neutral it is easy to remember to remove the key as I turn off the ignition.
