Those are tty special chars.  As of bash-3.0/readline-5.0, bash tracks
the values of the tty special characters and binds them to their readline
equivalents on startup.  This feature was added as the result of multiple
requests dating back to bash version 1.

It's not in the NEWS file (sorry, my oversight), but is noted in CHANGES:

o.  The code that initializes the terminal tracks changes made to the terminal
    special characters with stty(1) (or equivalent), so that these changes
    are reflected in the readline bindings.  New application-callable function
    to make it work:  rl_tty_unset_default_bindings().

The next version of bash will make this a settable readline option.
