Of course, if you do that, you can't use stock hoods on any of the lenses with step up rings. (And definitely never use this just for UV filters. They make almost no difference in any situation, where a hood can make a huge difference). This advice is best for very expensive filters that will primarily be used on your largest filter sized lens, and only on other lenses when the light is good enough that a hood wouldn't make much difference, or for lenses that don't have stock hoods where you can buy a screw-on hood of the appropriate length.
And remember that step-DOWN rings are also an option, if you're using a crop sensor camera and a full frame lens. (example: I have a few manual lenses with 52 and 55mm threads. I have metal screw-on hoods for them in the 55mm size and assorted filters in 55mm. When I purchased the 31mm ltd, it was my only actively used lens with a 58mm filter. I picked up a 58 > 55 step down, and they work without vignetting. I added a hood intended for a 50mm film lens, but that vignetted a touch with the step-down ring, so I should probably get a 58mm one and use a step-up ring at the end of the filters, just to keep things weird.
