I am for the opposite - removing the suffix when one is clearly the main station, and also unnecessary suffix, which include:
- Southampton Central → Southampton
- Southampton Airport Parkway → Southampton Airport
- Bristol Temple Meads → Bristol
- Cardiff Central → Cardiff
- Dover Priory → Dover
- Folkestone Central → Folkestone
And also removing the word International as it's misleading
- Ashford International → Ashford
- Ebbsfleet International → Ebbsfleet
- Stratford International → Stratford High Speed
The only situation a suffix is needed at a main station is when there are multiple main stations, such as London or Birmingham.
