Also, if some .elc file (outside the repository) compiled with the old
cl-defstruct breaks, there a backward compatibility mode that can be

    (cl-old-struct-compat-mode 1)

If there's a need to go beoynd that, I have a patch to bump the version
of generated .elc files (the number after ;ELC), and enable backward
compatibility as soon as an old file is loaded.
