Thanks, may I propose, and I think I will propose it in devel later today: Why not have a file called obsolete-var-funcs.el or backward-compatiblity-var-func.el That contains these old compatibility code? Such a file could be loaded by users who need this sort of compatibility? In my case such a file would look, for the moment (I have to run more tests) (define-obsolete-function-alias 'set-face-underline-p 'set-face-underline "24.3") (defcustom gnus-local-domain nil "Local domain name without a host name. The DOMAINNAME environment variable is used instead if it is defined. If the function `system-name' returns the full Internet name, there is no need to set this variable." :group 'gnus-message :type '(choice (const :tag "default" nil) string)) (make-obsolete-variable 'gnus-local-domain nil "24.1") -- I strongly condemn Putin's war of aggression against the Ukraine. I support to deliver weapons to Ukraine's military. I support the ban of Russia from SWIFT. I support the EU membership of the Ukraine.
