Generalised sizes are a deprecated way of handling screen sizes on Android, from version 3.2 onward we use far more traditional dividers such as minimum width. For many developers it's viable to support only 4+, which lets you avoid a lot of the trickiness.
Also, even if you are supporting 2.x, you don't HAVE to have a separate layout file for each generalized size. If you make a flexible layout that works on all sizes, you can just declare it once (and doing so is not difficult in most cases).
I totally agree the documentation needs work. Some areas have not been updated in a very long time.
