Think of it like code in an active open-source project. Someone needs to maintain the article

No, they don't, no more than Google Maps needs to "maintain" older versions of their imagery for access through Google Maps Timeline.

Curation should be directed towards informing the user and allowing them to make their own judgements regarding the content, not towards excluding content based on someone's completely-arbitrary opinion of "notability."

No matter how much hand-waving Wikipedia does on the subject, that's ultimately what notability comes down to: someone else's opinion.
