    if the consequences of that happening are not severe it might be worth the simplicity.

    The key part here being "if you use it right".
    I think the n string functions make it harder (but obviously not impossible) to "use it wrong".

    brewbuck:
    Is snprintf() a standard C function? I've never heard of it and I don't see it listed on this site: http://www.cppreference.com/all_c_functions.html
    Is it a C99 function?

    Yes, it is C99. I so often forget.
