@lina If you approach a large city with a plan to install a shiny new utility system, you will quickly find yourself dealing with a whole range of bureaucrats, some of whom will be more helpful than others. The kernel project resembles that large city in a number of ways. I don't say this is a good thing, but it is a thing.
I believe that the Rust for Linux project is succeeding. Yes, it is slow and painful, but the people pushing this work are doing the right things and making progress.
The city council (the maintainers summit) is meeting on September 17. Rust will be on the agenda, and there should be a couple of Rust for Linux developers there. That would be a good time to have a well-thought-out proposal for process changes that you would like to see.
