    I think it's attempt to save up on system resources, and also cost
    and firmware size reduction.
    You can build a device that looks shiny on the outside and put 5-8
    years old SoC inside with bare minimum EEPROM and RAM required for
    it to function.
    All manufacturers do that, gotta sell those stockpiled, but outdated
    chips somehow, and still make a profit.
    And besides, you can make it so there is no internal DNServer at
    all, just a simple iptables SNAT rule for port #53 hidden from end
    user behind a checkbox on the web interface named "Enable DNS
    relay".
