Yeah, the ONLY exceptions I've ever seen, either personally or anecdotally, have been in contiguous route transitions through separated trail systems in and around TM that might have arguably required at least the notion of some minor road travel in order to leave one trailhead and pick up the next, but NEVER an exception that allowed for an overnight in TM....hiking on beyond the restricted camping area is the price we've always accepted in the deal.
So yes, if anyone reading this thread (now or ever) has a differing opinion, and wants to test it out, you need to always remember that the wilderness ranger is the ultimate arbiter of your fate, and if it isn't clearly written and a logical route (that they know really well), or he/she thinks you're trying to pull a fast one, they're going to make it simple and cite you, and you can sort it out as to whose interpretation is the more correct in front of the magistrate.
