setjmp and longjmp are tools, that one may use in a good or bad way.
Along the same lines one could argue for dropping programs that use goto
in Fedora (because everyone knows that goto is bad). 

To the point, if a program uses setjmp and longjmp it is often that
there was no other way to do it. You cannot for example have a
co-routine/fiber implementation in C without setjmp() and longjmp().
