Thanks a lots for the instructions, I'll fix the patch when I get some time.
An very simple example you can try is

foo() {
    false
    echo foo
}
bar() {
    echo bar
}
foo || bar

which print foo but with default_connector_and_and on it will print bar.
If would write foo() more explicitly  when the shopt is on it would be
foo() {
    false \
    && echo foo
}
