There's a difference between having a "longer" hose and using a hog loop. Its the hog loop which creates additional complexity and additional risk, particularly when diving with recreational divers who dive only a few times a year on their summer resort holiday. These are the types of divers who most typically run out of air (OOA) or low on air (LOA).
When I worked as a DM at a resort, I expected to be the air donor, particularly for LOA air hogs in larger groups.
I set up my secondary octopus with a longer (just under 2metres) secondary hose, with the secondary octopus orientated as a left hand regulator. (Apeks XTX is great for this).
When donating, this setup avoids the awkward "S" hose twist, and also the risk of breathing the regulator upside down, which a right hand regulator creates in an air donation. It's also easier to swim side by side with the donee to the right of the donor. And the longer hose makes it comfortable for both donor and donee.
In my limited experience, for recreational open water diving, this configuration is the simplest and safest for air donations.
