I agree, unsafe rust is only meant to be used when absolutely needed. It’s up to the programmer. Frivolous use of unsafe should be rejected from any respectable code base.

I didn’t mean to say that without it the kernel would be irrelevant. I meant more that this is just one possibility for the future of the kernel and I think it’s important that we try as it has to always be better. Given the response from current maintainers I also question if the experiment should continue.
