This is another approach of the wip feature (and a good one because of the git native implementation). I used it before.
Unfortunately, I don't know why, sometimes my stash disappeared or because of a mistake, were applied to another branch than the original one.
Moreover, when you decide to go back to your working branch, you could forget (days after) that you created a stash.
With the above method, you'll be notified on your branch status, and be sure that your work will never be lost.
In the case you want to create a wip over another wip (which is very messy), I'm agree with you, stash with its history feature is the most efficient approach.
