I personally cannot stand the style/aesthetics - but that's just me. As well, a treble side rest seems utterly useless for a fingers (not thumb) player.
For bass side rests (particularly for my favored jazz/humbucker config), I simply prefer to use the neck pickup as my anchor and move up and down the strings as needed for sound.
As mentioned above, some like to use ramps to span that gap between pickups. They are not for me as I much prefer the two pickup look and have pretty much entrenched my use of the pickup as a rest.
Do what makes you a better bass player and satisfies your own needs, style, and aesthetics. No one else matters at all.
