[O] if featurep then require, why?

[Peter Münster]

Hi,

In `org-show-notification', there is

--8<---------------cut here---------------start------------->8---
  (cond
        [...]
        ((featurep 'notifications)
         (require 'notifications)
        [...]
--8<---------------cut here---------------end--------------->8---

Why is the (require 'notifications) needed?
