The BossStrap e-mails seem disingenuous and very vague, not to mention the support guys are likely to give a CYA answer. That said, I'd like to see something official from Nikon, Canon, et. al. At the end of the day, those customer support reps probably aren't in direct contact with the engineers/designers in their company, and this is something that should be addressed at that level. These kinds of straps are becoming more common and either the mounts should be up to the task or some declaration should be made on use of products like Black Rapid.
I'm no engineer, but work with a lot of them (insert "I stayed at a Holiday Inn last night" joke here). I think the issue would be more in the area of repetitive stress, but I can't really see how the kinds of load required to generate significant force in the socket are happening under normal use. Swinging it around with an 80-200 f/2.8 wouldn't be a good idea, but who is doing that? There is no force locking the body down or creating a "moment" at the mount. With the fastener in place, it seems like the stresses required to hurt it would have to be significant. Think of how low that mount is and how much stress would be involved with a 70-300 or similar lens mounted (that has no collar of its own).
The wedding forum post honestly sounds like user error to me.
Because I'm conservative by nature, and prone to destruction, here is how I set mine up:
Notice I put the safety strap on the highly unlikely to fail base ring on the strap itself - fastening it to the carbiner doesn't eliminate the likeliest point of failure.
The strap was $6 from B&H (I think) and could probably go to the standard strap mount on the side - might require a slightly longer version.
