Linus shouldn't have to get involved at all. Each part of the Kernel should be handled independently by the maintainers. Linus responding publicly to outside forces is fine but once he has to step in to handle public fights between individuals who are supposed to work together it is a problem.
Linux staying C focused is a valid thing to do. It is very hard to get folks to contribute to the kernel and if you cut out anyone who doesn't know Rust, a language with at best 5% the adoption rate of C, you will run into spots where sections of the kernel are unmaintained due to no willing and qualified person covering it.
Adding Rust based functionality and support is great. Changing APIs to require maintainers to learn Rust to continue to maintain the code they are experts in is unacceptable.
We have like three entirely reasonable shows all setup that they keep not even touching. All of them episodic, all of them able to both speak to new generations and old.
Upper Decks: Live action show with the characters from Lower Decks. Primary focus is the main characters coming to terms with the fact that they are good enough to be senior members of a crew. Continue the idea that they are the little ship that could and their missions focus around support rather than flagship or the biggest of the bads.
Prodigy 2.0: Again live action, with Ella Purnell as a captain who is super in demand and capable and would be fantastic in the role. Focus here is again episodic, when the rest of the Federation has abandoned exploration due to all the BS at the start of Picard, they are the only crew left with the charter to seek out new life and new civilizations. You have an incredibly young but capable cast and easily could bring in some heavy hitters to support them.
Legacy: This idea has floated around a ton since Picard S3, honestly its the least developed of the ideas and I'd rather see a way to roll it into one of the much better and more fleshed out ideas above. I feel like the final scene in Picard was an afterthought while both Lower Decks and Progidy it was a true capstone.
