[Too]

~/.(local|share|whatever) means I have to search both the basement, the attic and the garage. For stuff i rarely need to touch so I forget every time where it was placed.

If it was only one place it would be great. If it was truly separated by config vs cache it would be great. The reality know though is that you have at least three locations where important config are stored, not counting those from package managers that have their own idea of this concept. Still, this mess is preferable to the even worse mess of hundred plumbing files spread on the living room floor.
