It's an interesting reflection on how the rail network and its services currently operate if we are talking about a stop that provides plenty of connection opportunities
not being a helpful thing

I think it's rather subjective though - I personally love the fact that it stops at Westbury since if I needed to go to Uni from Devon if staying with relatives it is a quicker option.
Meanwhile if say travelling from St Erth to Paddington in the ideal world you would only stop at Paddington

(reminds me of a certain 4 wheeled device commonly known as the car)
