Regardless as to whether Gnome "does well" in the regard of performance, you must admit that for some of us choosing a competitor like wlroots over one like Gnome introduces a whole new adventure in replacing all the features of Gnome with standalone applications to use with wlroots. Plus a tiling window manager is a totally different workflow.
Not everyone has the time for curating a desktop environment with individual utilities, and not everyone likes tiling WMs. i3 gave me an RSI.
It's not a particularly arduous "adventure". We maintain a list[0] of programs which use these protocols. And wlroots != tiling window manager: there are multiple wlroots-based compositors which do not use the tiling paradigm, the most developed of which is probably Wayfire[1].
Apologies; I misunderstood one of your links and thought sway had been renamed to wlroots.
To be clear the "adventure" I'm talking about is for replacing desktop environment niceties like the ones provided by gsettingsd and the tight integration provided between devices and the system management tools offered in full desktop blown environments like Gnome and KDE. I used i3 for six or seven years and it was never as nicely integrated as Gnome and I spent a LOT of time yak shaving to get it nice and keep it that way. Eventually I gave up. Gnome is really nice these days.
But maybe I missed the point of your original comment.
Gnome hasn't provided a good desktop experience since 2011. By the time they figure out how to stop sucking insofar as Wayland performance they will surely have discerned new ways to err.
There are other environments that have worked well for a decade and will work well for the next decade.
