There’s little to know customization outside extensions which are very powerful but prone to breaking. The gone mindset is to support basically one workflow and to make changes as it needs fit regardless of stability. Personally I like this, it prevents things from getting stuck in the past. Plus I’m not one for extreme desktop ricing.

Edit: also I’m a huge fan of declarative systems like nix, and with little to no support for layout config outside of their GUI tool it introduces and unknown variable for me
