I have the 21 and 22.ucode files and others which seem enough to run the wifi, but I've searched the net and can't find these files anywhere. Assume they are for wifi? Anyone give me more info on this, where to find the files and why I might want to?

It is not shown in your post, but it tries to load different versions and likely finally loads one. I think there is a download page in Intel website for firmware download in case you want the latest.
I'm pretty sure those are development versions of the firmware that the driver is searching for, and would load if it found them, but since it doesn't, just continues until it does find an acceptable firmware file. So it's normal output, nothing to be concerned about.
I understand. My worry was that required files were not being loaded. What I understand now is the first, second, etc choice was not loaded, but are not necessary to get wifi working. Did I understand correctly?
Perhaps they do not exist because I am aiming to keep the install as stable as possible.
It's a difficult task on a very new machine and some compromises had to be made to get things working, such as installing the 4.12.1 kernel which isn't in the stable repository yet.
Can I assume that these files will be added to the stable repository as they are deemed stable? Or should I try to install from backports?

The kernel driver has a list of firmware it can use and tries to load the highest numbered one first then go down the line until it finds one.
You can get 29 ucode here https://wireless.wiki.kernel.org/en/use ... re_release
Download it to your home dir and as root
