It's not that disruptive even for backporting because %z modifier has been available for a long time so should backport fine.  This was mostly done with a sed script plus some hand fixups.

They are interchangeable and some places  used UINTX_FORMAT when they should have used SIZE_FORMAT.
Better to have just one and just use %zu, which looks better in the format specifiers. I'm going to do SIZE_FORMAT next but still negotiating how to handle review tedium.

The error message can be confusing though because the error message for %z refers to size_t.   But some of our use of intx should probably be size_t.
