You are absolutely correct. Long hoses are for one thing and one thing only, to get two divers out of an overhead environment in an OOA situation safely.
Period.
Using a long hose in an open water situation is dangerous and unnecessary.

I would like you to defend this rather absurd claim of the long hose being dangerous in open water with at least one example where it has caused injury. Even a reasonable hypothetical would be interesting. Your comment is striking in how arrogant it is, especially considering considering it's extremely dubious logic.
The recreational long hose (5-6 ft) is in my experience more comfortable, more streamlined, and far easier to share air with than the "conventional" dive gear industry recreational set up. I have used it as a DM in the caribbean with a wide variety of OW divers, shared air with a few of those.
To the post about the octo/inflators accomplishing the same thing; their use is similar IF you put the primary on a long hose, with 2 exceptions that I think are important. One is that you cannot start breathing off the octo/inflator with no hands, while with the bungied alternate you can just dip your chin to get the reg. The second is that venting air is somewhat complicated while sharing air. You can practice it, but it's still different than having two separate devices for breathing and BC vent/inflation. Plus, I find that a short (12") inflator hose is very convenient and streamlined over my left shoulder, really easy and quick to vent. With an octo/inflator, you must use a longer inflator hose, and I personally don't find that nearly as comfortable or efficient. Then you have the much larger inflator mechanism which is constantly on your chest; overall to me there's just no advantage to the octo/inflator. Dive shops sure love to sell them though.
