We were cleared to land on [Runway] 30L left and; while in the rollout; the Captain noticed an aircraft at A9 crossing the runway.  We were never informed of LASHO but the aircraft behind us was informed of a LASHO for them.
I was the Pilot Flying [PF] flying a visual approach to 30L at MSP.  We received radar vectors to final and were stabilized and configured at 1000'AGL.  Around 500' AGL; I heard Tower give the other carrier behind me a LAHSO clearance to 'Land on runway 30L and hold short of taxiway A9; traffic to cross down field.'  At approximately 200'; I heard Tower clear another carrier to cross runway 30L; traffic would land and hold short of A9.  I was in the flare (below 50') when the other carrier crossed in front of me way down field.  I landed normally; applied normal braking and cleared the runway at taxiway C and went to the gate uneventfully.  We were never a conflict with the crossing aircraft and I think it was crossing at the far end of the runway after landing on Runway 35.  However; we're not allowed to participate in LAHSO clearances; so why did the Tower cross an aircraft in front of me while I was landing?  It seemed he just gave the LAHSO clearance to the aircraft behind me; but left me out of the loop because our Company doesn't participate in LAHSO.  It's kind of disconcerting to see an aircraft in front of you while you're in the flare; even when he's way down the runway.  We need to either participate in LAHSO or get a clear runway to land upon; not a mix of the two.  There's potential for a late go-around or overly aggressive braking and a blown tire when the landing aircraft isn't given the full ATC picture.  Besides; landing data is based on the whole runway; not holding short of A9.
Pilots report after landing at MSP they observe an aircraft crossing the runway.  Pilot was never advised to hold short (LAHSO); but aircraft landing behind them was.
