I agree that it's not really serving any purpose anymore. But I'd say there's not much of a reason to go out of our way to remove it from this repo. As part of the Widget Alignment and Documentation project and especially the task of combining our web component development into one consolidated repo we can just choose to not bring the gocam-selector component over to the new repo.
