Now that legacy layout has been removed, the name `layout_2020` doesn't make much sense any longer, also it's 2025 now for better or worse. The split between the "layout thread" and "layout" also doesn't make as much sense since layout doesn't run on it's own thread. There's a possibility that it will in the future, but that should be something that the user of the crate controls rather than layout iself. This is part of the larger layout interface cleanup and optimization that @Looriool and I are doing. Testing: Covered by existing tests as this is just code movement.
