This is not the "right" way to do use the service, the proper way is to extend this service
(as described in the manual) by:

--8<---------------cut here---------------start------------->8---
(simple-service 'add-extra-hosts
                hosts-service-type
                (list (host "192.0.2.1" "example.com"
                            '("example.net" "example.org"))
                      (host "2001:db8::1" "example.com"
                            '("example.net" "example.org"))))
--8<---------------cut here---------------end--------------->8---

You only override the hosts-service-type value when you don't want to have
'localhost' as an alias of your _hostname_ or you don't want to set '127.0.0.1' / '::1'
as IPs for localhost / _hostname_.

This procedure is for internal guix use, it isn't really meant to be used outside.
In fact, I think it shouldn't be exported at all since it's only use is to set the default value of
hosts-service-type.
