Thanks Tim, As you can see, most of these are not "requirements" to run on a z/10, although some of them add new functions (which you are not using now). The only ones that are really necessary are the ones that add support for HCD and IODF definitions of the 2098. If you already have that support (by the check of HCD that I mentioned earlier) then you can safely run on the z/10 as you are now.
You shouldn't try to take advantage of features that you don't have support for (some hiperdispatch stuff), but you will run fine. There are some WLM stuff that pertains to kneecapped processors, but other than some odd RMF reporting issues, you won't even notice anything. The idea is that you are not going to stay at 1.8 for any long period of time, and you need to focus on moving to your replacement OS. This doesn't mean that you shouldn't bother to install these fixes, quite the contrary. You should always make every attempt to be as current as possible at your current OS level, because by doing that (assuming you already did), all of these would already be installed on your existing system. None of them are really that new.
