The hips could get better or worse from here.
Folks isn't there some healthy joint protocol that might be a good idea for this pup -- diet, exercise that will give this guy the best shot of reaching however good his hips can potentially be?
I have heard to use vitamin C, that the pup can absorb so it may be a special vitamin C, and there may be other supplements that promote healthy hips. Careful not to overdo calcium.
Regular walks, and swimming to build up the muscle tone, and do not force the pup to climb or jump. At the same time, let the pup be a puppy.
HD is genetic, but there does seem to be an environmental component to hip/joint health.
Good luck with the puppy. As for interference, I would interfere by adding the best supplement for joint health that people with GSDs recommend, and the exercise, and by not doing agility or anything like that until he is quite full grown. But no surgery. What would you do surgically to those hips? They do not look bad at this point. Yes, some puppies are loosey goosey at times.
