I thought 6a was supposed to support 10 Gig/500MHz over 100m.

To avoid signal feedback/FEXT from terminations being close. Presumably this started being discussed once cables had to certify @ 250Mhz and up. Far as I know, there's a recommendation (not an obligation) from EIA and ISO to that effect. Had a long discussion with a guy from Fluke some time ago, apparently they were considering offering the option to test for this in some of their models.
Seems like the engineers decided at the time that if the installation was done properly, with all channel elements conforming to the standard, there was no pressing issue. Don't know if they changed their mind now that Ghz-certifiable twisted pairs (cat7) are on the horizon.
On cat6 installs, I always try for a minimum of 45-50ft between terminations when possible, just playing it safe. Ofcourse that's not always feasible.
