I'm sure there's an oddball hub or two out there that doesn't conform to the norm, but IME they're all assymmetrical. Unless you put the effort in to track down something special, that's what you're gonna get.

"Makes sense" is a tricky thing to answer. For most riders, bikes have ample safe margins and will eventually be discarded due to other reasons than simply running out of life.
While building wheels that are theoretically more durable than average certainly makes sense from one perspective, it won't do you any practical good until you've ridden them more than average.
While JRA (just riding along) there's little-to-none benefits from having wheels that are more durable than needed.
