You will most likely see more teams only be able to be fed from the feeder station. However, your question makes it seem like a robot who can pick up from the ground won't be able to be fed from the feeder station. The advantage of having floor pickup is the discs on the ground during auton and picking up missed shots. If there aren't missed shots in a match, most teams will still be able to be fed from their feeder. And if it is found that picking up off the ground isn't worth it, the teams with pickup mechanisms can simply deactivate or remove them from their robot completely. If it is found that they are super helpful, teams without them are going to have a harder time to adapt.

In conclusion, more teams will be going to feeder stations, picking up from the floor has a good chance to be a game winner (auton).
