Here's a pic I snagged today of a White Oak in my yard. It has two large stems that "Y" at about 6 feet high.
I put this 3/8" log chain up as high as I could and still have strength, to hold the the union together. The union has a seam in it, the tree is by buildings and the canopy is substantial, that is why I chained it.
I use this method instead of cabling, because it doesn't require drilling through the tree and I believe it will last longer. Also, when the tree is finally ready to come down, I will pull the chain and put it back to use in my chain arsenal.
The chain loop is sized to each side of the tree to allow for growth, it is also pulled hand tight and secured. I didn't use grab hooks, just threw some bolts through the links. I think the best way to secure it would be to wrap the loose end of chain around the other like you are making a timber hitch and then bolt it.
I have done this before with favorable results. Girdling seems to be at a minimum with no adverse affects from it. The chain just kind of sits in one spot and will tension in a good wind. Nobody notices it unless you point it out.
This system seems to be close to those new cobra or whatever they are systems.
I have not seen it done, it's just something we do, so I thought I would throw it out there.
