Well, it is only unsafe if people used it without knowing what they
are doing, so I think a wholesale automated replacement is both
unwarranted and inadvisable.
I can recommend the following macro for the static buffer cases, it
checks if people know what they are doing with an assert.
#define bprintf(buf, fmt, ...) \
do { \
assert(snprintf(buf, sizeof buf, fmt, __VA_ARGS__) \
< sizeof buf); \
} while (0)

Never attribute to malice what can adequately be explained by incompetence.
