If you are running binaries for another architecture via software emulation (for example qemu running x86 binaries on your S/390 transparently) then you want exec only binaries to work with an otherwise trusted interpreter [Getting the interpreter trust stuff right is really hard btw - so ironically it probably has to be setuid anyway so you can't steal the handle]
