If these ever became a real fastener on a vehicle I worked on, I don't think it would be a deal-breaker. I mean, I forked out for the Kommen E53 sub-frame tool - what's a couple of sockets in comparison!
(BTW, I've used this Kommen tool precisely once (well, four times...), as pretty much any E53 owner would only ever do. But it's SO nice I can't bring myself to sell it!
)
