Only for another problem to crop up if you had passengers waiting for that train there or on that train who would now be overcarried.
Trains shouldn't just miss stops due to lighting issues, some TOCs will instruct their traincrew to stay in the platform a extra minute to provide some form of lighting from the train.
Apart from that, usually the call goes out to the nearest manned station for portable emergency lights to be sent with a member of staff to that station after which trains call as usual.
With a 3 car 313 on a stopper with a conductor on a Seaford working - absolutely - dwell as much time as is needed to allow people safely off the platform using the train lights and most people will be happy and reasonably safe.
Any train relying on using D.O.O. in cab images and the can of worms you open is a catering size can. As has been touched on, the lighting at stations where on board cameras are used is set at quite stringently applied levels so degraded despatch will almost certainly consist of a walk back at the very least.
With a 12 car and an OBS not despatch qualified, that's a lot of dwell time on any route with a busy service to have a significant impact.
Some locations with mirrors and platform monitors muddy these instructions even further, not least of course because a power failure may shut off platform mounted monitors. Ambient light and local knowledge plays a huge part and most importantly, Safety has always been at the back of my mind in the literally hundreds of times I have had to "make a shout" about these scenarios.
That problem rests on others shoulders these days.
