I disagree because mktemp offers the functionality of just creating the file name and instantly unlinking it thus only providing the generation of a random name. While I don't think that many scripts rely on this it can be the case. --with-libc is not used by some vendors because it limits the template used for the file name. mktemp from coreutils should be a better choice any way...
