I don't see how you arrived at that conclusion. A user who is
content to normally create world-readable files by default is
nevertheless not very likely to want his temp files created with the
same liberal permissions; he might elevate his security at times by
working on sensitive data within a mode 0700 directory, or he might
merely have a single secret text file with mode 0600.
If that data is exposed through a world-readable temporary file,
something is _wrong_, umasks notwithstanding.
