Indeed I do not think there is any defined access at all to the standard readtable other than that (copy-readtable nil) will make a copy of it which you can then modify.  Whether or not something which is not programmer-accesible is immutable or not is kind of a moot point.

Oh, but it is verily accessible, with WITH-STANDARD-IO-SYNTAX,
and that was causing some grief indeed.

(defvar *standard-readtable* (with-standard-io-syntax *readtable*))
(defvar *standard-pprint-dispatch* (with-standard-io-syntax
*print-pprint-dispatch*))

I'd go as far as to recommend that unreadable such tables
should be made the default while loading Lisp files,
unless explicitly overridden using named-readtables and such.
I should ask the cl-syntax author to add support for pprint-dispatch tables...
