Is there a way to get away from such a requirement, Eli? If unexec becomes
untenable in the future, is there an alternative that doesn't place the burden
upon us to encode the right amount of information in the dumped file?

If I understand Daniel's contribution, he's proposing the equivalent of a
program loader for Emacs Lisp byte-code, stored within what amounts to a
custom object file format.
