You are right, but if I want to tell people that here is zsh, just link it
to sh and use it, they will complain that it brakes this and that.  Fixing
a program is easy, but finding all programs depending on this feature is
difficult, and even if you do find everything, old installations will still
have some old broken binaries.  For the same reason has zsh so much obscure
bug compatibility code.  And some Linux developers simply tell you, that if
/bin/sh is not bash, then your Linux system is broken anyway.

Perhaps there are'n too many programs using brace expansion, but I have
even seen a program using this in a system() libc call )-:.
