No.

This patch/bug report addresses a real problem that exists independently
of what triggered it in my case.

Your gut's nearly certainly right here :-)  I am still hunting for the
cause of that issue.

Regardless, what I said initially holds true ultimately: either epa-file
should not be relied on, or a-s-p should ensure it is present.  I
gravitate towards the former, as it reduces the complexity of getting a
password-store entry.

That is too verbose.  The following appears to work well, though:

--8<---------------cut here---------------start------------->8---
(add-variable-watcher
 'file-name-handler-alist
 (lambda (symbol newval operation where)
   (cl-flet ((hefh (val)
	       (seq-some (lambda (x) (equal (cdr x) 'epa-file-handler))
			 val)))
     (let ((hb (hefh file-name-handler-alist))
	   (ha (hefh newval)))
       (cond
	((and hb (not ha))
	 (debug--implement-debug-watch symbol newval operation where))
	((and (not hb) ha)
	 (message "epa-file added")))))))
--8<---------------cut here---------------end--------------->8---

Have a lovely day!
