Cosmic Desktop by System 76 is really excellent. I've been using it for a little while now. I believe its still in pre-alpha, so take that word of caution but it does window tiling exactly the way I want with modern but minimal chrome.

i have an eye on their ecosystem too, mainly because it's build in Rust. hope they release something usable soon (the terminal for example)

Redox OS is another interesting Rust experiment and they recently started using Cosmos Desktop with it.
