As I wrote, I'm also okay with Someone™ volunteering to reimplement
this option such that it invokes basic-save-buffer instead.
A minor mode that you describe would also be fine, but then it should
probably disable auto-saving if auto-save-visited-file-name is set,
right?
Sounds reasonable. I'll try to come up with something by next weekend. Probably it will be just
(defvar auto-save--timer nil)
(defcustom auto-save-visited-interval 5
"seconds"
:group 'files
:type 'number
:set (lambda (symbol value)
(set-default symbol value)
(when auto-save--timer
(timer-set-idle-time auto-save--timer value :repeat))))
(define-minor-mode auto-save-visited-mode nil
:group 'files
:global t
(when auto-save--timer (kill-timer auto-save--timer))
(setq auto-save--timer
(when auto-save-visited-mode
(run-with-idle-timer
auto-save-visited-interval :repeat
#'save-some-buffers :no-prompt
(lambda ()
(not (and buffer-auto-save-file-name auto-save-visited-file-name)))))))
but it will also need tests and documentation, which take a bit more time.
