Well, if casting to intmax_t is narrowing I think I have bigger
problems on my hands :-)

I've spent a fair amount of time agonizing over this in Varnish and
I came to the conclusion that the my time spent trying to establish
if something narrower than intmax_t was safe would never amortize
the performance difference of printing an intmax_t vs. intN_t, so
now I just cast anything that that's typedef'ed to intmax_t and
move on.
