Fair point in general. But if you run the numbers, 4.56 for 37s is pretty close in gearing, through all the gears, to a stock auto with 32s and 3.73 gears. Actually a little lower, almost like with 4.10s. And remember the 4.10s aren't even considered necessary on a Rubicon, they're optional for the auto. (Makes me think Chrysler doesn't think they match up well with the 5 speed).
Look at the numbers below, which make me think a lot of people are actually OVERgearing compared to stock...
This is 4.56 with 37s vs 3.73 with 32s.
Then 5.13 with 37s vs 3.73 with 32.
