This is really nice and straight-forward, thanks!

I see one problem here.  It basically splits the require up in two:
I need to look both at the start and at the end of the file to
understand what is going on.

In the previous discussion, Adam Porter suggested this:[1]

    (shorthand-require 'magnar-string :with "^s-" :as "magnar-string-")

I like that proposal a lot, but it's a bit too verbose for my taste.
It also seems to flip the :as and :with from what I would expect (in
Python, "import x as y" means that x is available "as" y in this file).

In my ideal world, we should be able to just say simply:

    (require 'magnar-string :as "s-")

There could be a variable inside magnar-string.el that gives us the
rest, e.g.:

    elisp-default-import-prefix: "^magnar-string-"

WDYT?
