The way it's designed, is to be staked. It's nowhere near an "added complication." Not even close. It's also quite easy to remove a properly staked castle nut. No staking comes into contact with any thread material at any time, either. It's lockplate to castle nut, on the outer edges. If you have to remove it, and think it's unsightly because it was previously staked- you just replace the receiver end plate with a new one. They're cheap.
Have you ever staked one? It kinda sounds like you don't know what I'm talking about.
But, hey, put loc-tite on anything on your gun that you want. Do it how you want to. It's not the right way to do it, but it's Burger King day, and you have it your way.
