It's more appropriate to use 'for-each' here.  'map' collects all of the
results into a list and returns that list, which is not needed here, and
is slightly less readable.  Also, the second argument to 'find-files' is
optional; omitting it does what's needed more efficiently.  So, in the
interest of promoting better practices, I would recommend this instead:

--8<---------------cut here---------------start------------->8---
         (add-after 'unpack 'make-writable
           (lambda _
             (for-each make-file-writable
                       (find-files "."))
             #t))
--8<---------------cut here---------------end--------------->8---
