I think that it is some legacy issue. Perhaps the original idea was that
routes learned from kernel were some initial routes used during boot,
which were later replaced by routes from dynamic routing. But as BIRD (on
Linux) currently do not allow to overwrite alien routes anyway, it would
make sense that these routes would have higher priority, like static
routes.
