The ups and downs of strlcpy()

You wrote such a long article to say the "up" and "down"s to justify "strlcpy()" not going into glibc, and the ONLY "down" side you points out in the article is "if you do not check the return value of strlcpy(), then you can lose data"? Sorry, this seems an very far-fetched argument to me, since how many C library functions can do EXACTLY what you want it to do WITHOUT checking return value and handling the error accordingly?
