It's pretty terrible. I've feuded with more GNOME maintainers than one person should ever have to, and it always comes down to the same "well we're right and you're wrong" mentality that makes nobody happy. With blurry text in particular, a surprisingly large number of GNOME team members decided it wasn't an issue since the effect could be halfway mitigated with sandboxing, so none of them ever addressed it.

I can't use GTK4 or libadwaita confidently, as a developer. It's tooling that was designed from the ground-up to limit my capacity as a developer, and as such I refuse to write code with it or install it on my system, for that matter.
