Thanks!  That's the missing piece of the puzzle.  I've now extended the
doc strings of these two variables to mention each other.

Indeed.  For future reference, the feature request can be achieved by
something like

(setq command-error-function
      (lambda (data string func)
	(unless (eq (car data) 'end-of-buffer)
	  (command-error-default-function data string func))))

to display all error messages except `end-of-buffer'.

So I'm closing this bug report.
