That may be what you want but the OP thinks that new services from Catford will reduce demand on FH - London Bridge. Not good for Forest Hill/Honor Oak and a campaign tactic that uses sacrificing our line to boost theirs.

There is limited capacity and we're in competition. At the moment we're getting overlooked and a proposed inferior service. Forest Hill is much the busier station and the Forest Hill/Sydenham corridor much the busier route. The priority for Southern are long distance commuters. They spend more.
