Does it look correct to you?

Do you know if it's possible to delete the bundled copies of libxml and
libunistring entirely?  I got build errors with this source snippet:

--8<---------------cut here---------------start------------->8---
              (modules '((guix build utils)))
              (snippet
               '(begin
                  ;; Delete the bundled copies of libxml2 and libunistring.
                  (for-each delete-file-recursively
                            (find-files "." "^(unistr|libxml)$"
                                        #:directories? #t))
                  #t))
--8<---------------cut here---------------end--------------->8---

Anyway the new gettext does seem to work fine.  It has grown from 78.9
to 97.9 MiB (this is on the 'core-updates' branch):
