So, you call protocols outside world? Did i understand correctly?

I agree, that situation is quite symmetric, but when you are inside
(protocol definition) then export means "go out of here" (to routing table).

Your point of view is developer's. You see "core" routing table as a

This is certainly caused by configuration file, because there are not
configuration commands for "core" routing table.
