Not the ones from the distributions.
There are many features that I consider enterprise ready, congealing in the 2.6 kernel. In any cases, they were externally available in the distributions for quite some time, just not RH, which is where I'm forced to be.
But of course, we will will not "move" to AS 4, but be stuck with AS 3, for quite some time. No direct upgrade path, and I would not take it even if there was. I assume the next Linux server we install will try AS 4, but it will really depend on the 3rd party applications be certified on it.
I have no argument with your description.
Like I titled my post, "My uninformed take on the matter".
