And that exactly the point why they should release it. Currently you can basically use it for 4 things:
- Notification
- Camera light
- Torch
- And Uber arrival 🤷♀️
There are so much more options if the API would be known. For example why not do the same you can do with Uber for the rest of the public transportation. Or like for Food delivery services.
Currently the glyph thing is more or less a party trick but nothing useful. With opening the API it could be integrated in so much more Apps so it will become useful.
P. S.: Only the hardware is unique and relevant for marketing. To make it accessible for all developers would just increase the marketing of these extra lights.
