No if it's a usage error on the helm side which the older EIEIO simply
ignored, then I'd suggest not to reinstall compatibility with that older
version but with CLOS, i.e., signal `cl-no-primary-method' instead of
`cl-no-next-method'.
Oh, and I see that Thierry (the helm dev) already added primary methods
in
https://github.com/emacs-helm/helm/commit/1eb07354f50ec26aa8be1290233696656b8dca32
So I'm closing this bug.
