I've seen a lot of strlcpys, and of that I think I have seen maybe one place where the return value was used. I think if you asked people why they used strlcpy, 95+% would say "security" and then list out the characteristics my strxcpy has, rather than "I want snprintf-like behavior with a size_t return" which is what strlcpy is. I would not be surprised if most people got the time complexity of the function incorrect because of this.

If the return value of strlcpy isn't used, the compiler can optimize the extra inefficiency away. (I don't know if any do, though.)

This is similar to how strlen(x)>0 calls get optimized to *x by clang and likely other compilers.
