But, in my defense, I did say "software that could be useful to folks with accessibility needs that don't try to address it (within bounds of their resources and capabilities, obviously lots of OSS just doesn't have the ability to deliver an accessible experience for tiny little throwaway apps)". If that aint you and that aint the software you're making, I'm not talking to you. And, sometimes accessibility isn't just for blind users.
Literally all of them are using it as part of non-user-facing debug tools for 3D graphics:

Meta as part of their VR/gaming division, Google in their VR division and 3D rendering engine, Ikea in a 3D material editor, and Intel in a 3D SDK.
And again, the intended use is immediately explained on the project repo no matter what the comment you were replying to said.
