Double checked for National Harbor, and yes it's not showing any tier matching promotions. Don't see any recent data points for it either on other gaming forums. Most recent data point I saw was from March. But MGM Springfield is not the only property. Borgata at Atlantic City has been tier matching ever since they got bought by MGM. Gold Strike and MGM Detroit occasionally does tier matches and has different promotions running to include freeplay. Though they are all part of MGM, each individual property runs their own promotions in regards to tier matching, unlike Caesars where it's more universal.
To OP, belay my last on tier matching at MGM National Harbor. You can always try to call to see if they are and just not advertising it. Your other closest MLIFE location would be at Borgata Atlantic City, which is around a 3 hour drive away. The trip may be worthwhile and could be a nice short weekend getaway.
