It's important alright, just the same as the following examples - Lever pivots, footpeg pivots, hydraulic rear shock preload adjuster screw, seat latch pivot, just to name a few. They are all mundane, but they make a big difference to the overall condition of the bike over time. We could start a "pivot lube" thread. 
My tip for the day (maybe we could start 1 of those too) - if you don't have a bike cover and you are out in the rain overnight, cover the throttle with a plastic bag and tape it in place. Keeps out the rain.
