For better integrating/onboarding newcomers, it would be useful to pre-populate their watchlist with a handful of important pages, such as village pumps and their equivalents.
E.g. All new self-created accounts on a wiki could have the local village pump (and helpdesk, or anything) watchlisted, by default.
E.g. When a new [chapter board member, or developer on a specific team] has a new account created, the account creator could add a list of pages like "other board members' userpages and the village pump", or "other team members userpages and relevant extension pages" to that newcomer's watchlist.
(The current manual alternatives are: Create a list, and ask each newcomer to either copy&paste that list to their own [[Special:EditWatchlist/raw]], or to visit and watchlist the pages one by one.)
