I was not keeping up with the previous version’s discussions, but this PATCH v2 LGTM. 🚢

As for the Emacs script, maybe change defun password-store-dir to something like this:

(defun password-store-dir ()
  "Return password store directory."
  (or (bound-and-true-p auth-source-pass-filename)
      (getenv "PASSWORD_STORE_DIR")
      (if (file-directory-p "~/.password-store") "~/.password-store")
      (when (getenv "XDG_DATA_HOME") (f-join (getenv "XDG_DATA_HOME") "password-store"))
      "~/.local/share/password-store"))
