It's not a problem of distance or amount of nodes but a problem of
amount of 'ways members' . In France, the national boundary is the sum
of all (small) municipalities boundaries. Themselves are often split
because our neighboring countries have the bad habit to use different
limits for their municipalities ;-)
Boundary relation for Russia is currently about 600 ways members where
the boundary for France is about 2600 ways (excluding overseas
territories).
