    Why should orbital chaos respect planetary size? High eccentricity orbits abound in extra-solar planetary systems.

    Perhaps the worlds were more or less earth sized to begin with and migrated inward.

    Energy is minimized by larger bodies becoming more tightly bound gravitationally. So that is favored statistically.

    Perhaps the worlds were more or less earth sized to begin with and migrated inward.
    Perhaps, but not favored energetically or statistically.
