yes, and there's support for u/i/o/X/x/etc modifiers

it depends on what you are trying to target. that's why i bring up
standards as soon as you start talking about this. size_t and
ptrdiff_t are part of C. ssize_t isn't.
ssize_t is a posix-ism and is defined to store "values at least in the
range [-1, {SSIZE_MAX}]". If you care about what C says, then you can
do anything you want with ssize, because it isn't part of C. For
printing, %zu is size_t (per C) and %zd is ssize_t (per POSIX).
