The goal is not to use a similar tech stack e.g. GNUstep. Instead I'm focusing more on outcome - a desktop environment with a similar degree of polish and functionality without the need for third party tools.

To stay competitive and iterate fast I'm adding a high-level JS/CSS API on top of Wayland, think AppKit + SwiftUI. If you look over my shoulder it might look like I'm making a webapp, but on a custom browser.
