Do people not also (confusingly) use "the 1900s" to refer to 1900-1909?
That's definitely the case, so I'd support a style (either policy, or informal policy) if using "the [[20th century]]" instead of "the [[1900s]]" for centuries, and [[1900s]] for the decade (although this latter usage is moderately confusing). It's not an issue that has much in the way of political or social ramifications, so NPOV is only really a minor point...
