I'd argue that we are already in this situation.  For example, nobody knows how to make unexec work with ASLR or PIE; when I tried fuzzing Emacs with AFL, the dumped binary would simply crash; the dumped binary is not reproducible (i.e. bit-by-bit identical after every build); and I think dumping also doesn't work with ASan. The fraction of situation where unexec doesn't work any more gets larger and larger. If we had people who could solve these problems, it should get smaller instead.
