Why is getentropy marked with warn_unused_result?

Hi!
I recently opened a bug in the Qt project[1] because it failed to
compile on my system. The reason this happened is because it ignored the
return value of a getentropy() call, and that's marked with __wur.
Why is that, since it shouldn't fail under normal circumstances (at
least that's what Qt's sources claim)?
