Well, I didn't do a detailed survey into the ecosystem, but I think you might be underestimating the prevalence of setjmp/longjmp a little bit. For one thing, tons of stuff hard depends on libpng, and libpng only has limited support for environments without it, so that alone is a pretty hard limiting factor. But also, I already ran into two different very common libraries that need it. FreeType also needs setjmp/longjmp!
