CoreCLR doesn't help on console platforms because you can't ship the JIT runtime. To my knowledge CoreCLR's AOT solution won't work because of SDK and build requirements for shipping builds on consoles. I believe some consoles require that all shipped native code must have been compiled with the SDK compiler. Even if you fork the CoreCLR AOT system so you can build for the consoles (the code can't be open because of NDAs) you wouldn't be allowed to ship the binary. IL2CPP is the only path forward there. CoreCLR is only viable on PC.
