    I understand that it probably isn't an option to change the behavior
    of forward-line for compatibility reasons, but it could still be
    interesting to know the reason for the decision to return zero when it
    has moved but not managed to move to a different line.

It seems logical to me.  The decrease in the number of lines remaining
to be moved is zero.
