I have used all three as well. My favorite currently is a variation on "use a small screw." I put some of the alu foil around the pickguard screws holes. that way it is contiguous with the alu foil on the bottom of the pickguard. In turn, that foil is in contact with the pots. Easy to see if this is working by putting a multimeter lead on a pickguard screw, and the other on the jack nut.
I use a winder on my basses. I have used it more since I started building than all the time before that combined, however, which sort of makes your point ;-)I don't know anyone who uses a bass tuner winder (most bass players don't change their strings anything like as often as guitar players) strings , but they exist and angled tuners could stop them working if the handle catches on the headstock or the next tuner key because of the angle.
