This does sound appealing. But I think currently dh-elpa requires Emacs >=1:30.1+1. Will this cause some kind of a circular dependency that may break upgrades? If that's the case, I think we can change the handling in dh-elpa[1] to work for both 30 and older releases, and we can loosen that requirement so that it can upgrade before Emacs 30.1. > -- > Sean Whitton [1] https://salsa.debian.org/emacsen-team/dh-elpa/-/blob/master/dh-elpa.el?ref_type=heads#L102 -- Regards, Xiyue Deng
