Use of original Halo 3 launch maps

Obviously this is not a big priority at the moment, but still bugs me a bit.

In Halo 3 matches the maps used in MCC MM are Snowbound, The Pit, Epitaph whereas by Sept. 2008 (I think at TU1) these were replaced by Boundless, Pit Stop, Epilogue.

I think these versions are much improved and contribute to a better experience overall with less camping, better balance.

How do people feel about this discrepancy?
