Yeah, you won't be able to please everyone. So you really need to look at what it is you want to do and accomplish. Sandbox games often have a negative feel to them, so you will have new folks not even look at your game because they filter the tag out or see it and skip. If you want to grow your subscribers and you notice a general dislike of your sandbox (I saw one person comment on it in the thread, but that hardly constitutes a general dislike), then you can simplify your dev process and potentially bring more people in by removing it.
Subscribers typically love getting stuff early and being apart of the process, so definitely a viable option if they are active.
