There are situations where it is useful.  For example:

  M-: (char-after) RET

I don't think it's an oversight.  This is a user option, so its place
is generally on the user manual.  The ELisp manual has a
cross-reference to where that variable is described; the ELisp manual
mentions eval-expression-print-length and eval-expression-print-level
only because they are relevant to print-length and print-eval
described there.
