Why does MDS deactivate when stopped?

Seems like that would be the best time for MDS to be activated. No sense in running 8 cyls when you're not going anywhere, right?

There would be significant imbalance issues idling in 4-cyl mode. It would feel like the engine is mis-firing and most any customer wouldn't find that acceptable.

When the engine is turning at +2k rpm, the firing intervals (when MDS is engaged) occur frequently enough that you won't notice except for the exhaust sound change.
