    I think those uses of prin1 really call for some way to reliably print data
    in a lisp-readable form.  I.e. a variant of prin1 (or a way to tell prin1)
    that ignores print-depth and friends and which signals an error when it
    encounters an element that it can't print readably (e.g. a marker, a hash
    table, ...).

This is a very complicated project, and I think that with
the added complexity it would be a change for the worse.
