For a bit more context, here's what it takes to put an "Add custom block" button on each theme subtab of admin/structure/block:

If we switch to yml based discovery we safe quite a lot of all the use statements.
The main reason why this seems so complex is that we went with allowing appearance based upon routes instead of paths.
This will become problematic if you add a new route you want this plugin to appear on. Previously it worked automatically because it was based upon the path, but now you need to alter it.
