There may be good reasons to do that.

However readline (as you cited it in one of your messages) doesn't
work the way you want. For instance, if I create a .inputrc file
to bind backspace to the string "foo" and run "stty erase r", then
start bash, I get "foo" when typing backspace, and the 'r' key still
does the erase function.
