But this is exactly where the problem is, not printf per se, but
stdarg.

The promotion rules are simply archaic and of no good, nowadays. All
the problem would go away if all integer type parameters would be
promoted to [u]intmax_t, all data pointer types to void* and all
floating types to long double.

I don't think that this has anything to do with "low-level" nature of
C, but with a wrong design choice that we carry around as a legacy.

Not that I am against it, but what you are proposing is just a cure
for a symptom, one of many symptoms for that particular legacy.
