I don't think rebasing on to Linux offers them much. The current interoperability is "good enough", and the rest is UX - something Microsoft struggles with across the board. It's not for a lack of trying either, they've spent years now working on Fluent and it's still mediocre. Every time you think they make a fantastic decision, they turn around and add 10 more horrible UX choices (see Edge). It's so apparent it feels like as soon as the core design and dev team finalizes something, it gets sent to a penny pinching team who requires it have a bunch of unnecessary cheap bloat. This is something that won't change on the shift to Linux. It has to be a deep cultural shift, until then the company is never going to prioritize experience.
