intro-string in byte-compiled files

I wonder if the following code found in all byte-compiled files still
makes sense:

;;; This file uses dynamic docstrings, first added in Emacs 19.29.
(if (and (boundp 'emacs-version)
     (< (aref emacs-version (1- (length emacs-version))) ?A)
      (or (and (boundp 'epoch::version) epoch::version)
           (string-lessp emacs-version "19.29")))
    (error "`simple.el' was compiled for Emacs 19.29 or later"))

Emacs 19.29 was released 13 years ago. It is nice to be backwards
compatible, but as some point such things should be dropped.
