I’m not sure that’s a great way to think about it, but I understand the feeling – Teletype is a very deep module, and honestly think it’d be difficult for anyone to use all of it’s functionality all the time. For instance, I sometimes feel I’m underutilizing the remote-control aspects of it, since I don’t have it connected to my White Whale or Earthsea. But ultimately that’s not really what I need it for, and that’s all that matters in my opinion.
If you have space for it in your rack, and think it will be a nice complement to your existing modules, I don’t think you need to worry about utilizing all, or even most of it’s features. In addition to it’s existing depth, since it’s an open-source project, new features are being added all the time by the amazing community, and I haven’t even scraped the surface of what some of those new features can do.
After having Teletype for a couple of years now, I can say it’s one of my most essential modules in my rack.
