IF you shoot an f1.2 lens wide open in a daylight setting, you will need one of two things and probably want both for separate reasons/situations -- and they are:
1) a shutter speed of 1/16,000th for ISO 100 and 1/32,000th* for ISO 50/64 base cameras; AND/OR
2) a 3-stop ND filter for said lens.
*Caveat: Some locations are actually brighter than Sunny 16 by a full stop *or more*. Notably Southern latitude regions in clear air conditions like Phoenix or San Antonio or Santa Fe; or high altitude locations in clear air like the Sierra Nevadas or Colorado Rockies. So here, even a desire for 1/128,000th could be justified... (Hence my condition above for including the 3-stop ND filter in addition to the 1/32,000th shutter speed.)

Dan, while I agree with your main points, I think discussion about the reasons why some folks want or even feel the need for more than 1/8000th is definitely worthwhile -- even though it may be a bit more spirited than it needs to be
