I wish the likes of Nintendo and Sony themselves finance such efforts. I mean it's one another way to create games (IP) for your console, what possibly could be the downside of starting something similar to Github Accelerator for your platform?
At least there isn't as much hoop jumping as there used to be, since the systems have all converged on using commodity CPU and GPU architectures with at most minor embellishments.
I wish vendors would be just more supportive of different llvm tool chains. Rust isn't even well supported.
Same applies to Rust on Windows, and whatever Microsoft is doing, windows-rs isn't that great, and after what the team did with C++/WinRT I don't have high expectations.
So consoles have even less reasons to support Rust.
That is why we cannot have nice things.
