This exact thing happened with x11, you clearly have not researched the history of this.
Your app will work across all of Wayland, the reason this happened is because wlroots came out after gnome and kde made their implementations… kde and wlroots have worked together to the point where kde’s compositor is almost identical to wlroots. The only apps I’m aware of that don’t work are display managers but that’s only because the protocol for that hasn’t been stabilized yet.
