There's rubble.

We've been approached by multiple parties to finish it and we are up to it, but the final effort, particularly certification is currently prohibitive. Serious inquiries taken, though - we're also happy to play "consortium" in that this does not have to be financed by any single party.

I'm just a hobbyist, so certification is less important for me as long as it works for what I need. BLE 5 would be nice but more important to me is an HID service that's fairly complete, but that doesn't even seem to be on the roadmap. It's going to be quite a pain if I had to implement this myself.
