Right. A huge part of the value proposition of enterprise kernels is the stability, which you pay a cost for in the form of backporting and maintenance. That’s the thing that makes it valuable as a product!

It really can’t be the policy of the upstream to restrain enhancements because they might make backports harder. Companies get paid, and paid well, to do those backports! Let them be responsible for that burden.

To what? The article outright mentions that Rust support is still experimental at best, nor is Nova anywhere near ready to get merged into the mainline kernel.

I believe they're creating the vGPU functionality, which means they're working with what exists (at the current time). nouveau is in the kernel, and is also backportable and used existing kernel tooling (including the compiler), while nova is neither.
