Are Sector Values from MapSizeDefs.xml even used anymore?

For example, the following results in the corresponding map being generated.  

In this case, I explicitly set 8 Medium Sized Sectors to be generated.  But that is not what I get.

   <MapSize>
        <InternalName>Huge</InternalName>
        <Width>2928</Width>
        <Height>2928</Height>
        <Sectors>
            <MinSectors>8</MinSectors>
            <MaxSectors>8</MaxSectors>
            <AbyssRadius>100</AbyssRadius>
            <SectorsOfSizeCount>
                <UniqueID>Tiny</UniqueID>
                <MinCount>0</MinCount>
                <MaxCount>0</MaxCount>
            </SectorsOfSizeCount>
            <SectorsOfSizeCount>
