Move nodes, deprecate them, yes, but also maybe fix bugs/typos etc...
For most of these, of course, fixup code can figure things out without a
version. The version has a couple of (minor) advantages, such as being
something easier to get into a bug report rather than the whole tree,
for distro who may want to manage a "pool" of these, or maybe a
"generic" way to provide dtb "overrides" ...
