The London train has a good connection into the 0812 BPW» (Bristol Parkway - next trains) - WSM, so not too bad an option for S Wales to Filton Abbey Wood or Temple Meads. Would help if there was an announcement at Newport that passengers awaiting the Portsmouth train might like to catch the London train instead: only when the Holyhead train has left P4 does the train indicator board say how many carriages will be on the Portsmouth train, by which time the London train is already on the approach to P3.
