It's worth noting that the setup on Strats and Teles often improves with a neck shim too, and almost all of the old ones came out of the factory with shims. Hell, even my '04 MIM Strat came with three paper shims in it. There's nothing odd about using a neck shim. It's actually quite normal on a Fender, even from the factory. And if you were to examine the innards of set neck guitars, you'd likely be surprised at the number of shims you find too.
In other words, the Jazzmaster and Jaguar are not really special in that regard. It's just that, due to the more complex bridge design, they suffer more if you pull the shim/s out. It's also the case that Strat and Tele bridges handle the low tension of modern strings "better" than the Jag/JM bridges do. Remember that these guitars were designed around flatwound 12s. 12s are tighter than the 10s and 9s that most people use these days, and flats are also tighter than rounds. So most people are using strings that are 2 to 4 gauges lighter in tension than the guitars were designed for. That's like putting six inch wheels on a 500 ft-lb hot rod that was designed for 10 inch wheels, and expecting it to perform OK. Sure; it'll drive, and it'll stop. But you have to stay within a certain range, nowhere near its performance limits, or else the thing won't work very well.
