The standard readtable isn't writable unless you go out of your way to access the magic standard readtable.
So, it's perfectly valid to modify *readtable*.
Or are you suggesting that *readtable* should be eq to the magic standard readtable?
The same holds for *print-pprint-dispatch*---it's a copy of the standard dispatch table, not eq to it.
I am suggesting indeed that, as per the CLHS for WITH-STANDARD-IO-SYNTAX and the CLHS Glossary for standard reatable, W-S-IO-S should bind *READTABLE* to the standard readtable, and similarly for *PRINT-PPRINT-DISPATCH*. And for the sake of sanity, said standard tables better be readonly.
