Would it be worth the effort, and how feasible is it anyway?
- Do we have any usage statistics?
- How often do we see bugs caused by bad uses of setjmp/longjmp?
- Is mitigation instead of blanket removal possible?
- How likely is it that /all/ setjmp/longjmp uses can be reasonably 
- Is there existing upstream momentum to move away from setjmp/longjmp?

(I'm not against the idea but I think it deserves further discussion.)
