I noticed that, with the recent fulfilment of phab:T263821, a feature was added that allows you to subscribe to any new discussions that are started on a talk page. This is super useful! I'm employing it at pages like w:WT:Teahouse (where I want to know about discussions about the Teahouse itself but not to be notified or have it show up on my watchlist every time someone asks a question).
However, there currently appears to be no way to keep track of which pages I've subscribed to new topics for. Given that this is a sort of quasi-watchlist feature (similar to incoming links, something we've long wanted), I'd find it useful to see a list of all such pages.
I would use this list to help identify possible additions (i.e. seeing the list might remind me of similar pages I'd like to add but haven't yet) and to more easily prune (i.e. I might notice pages I no longer want to subscribe to). Its presence would also be nice in the sense of reassuring me that I have control over my data should I ever want to use it (similar to how I appreciate the existence of w:Special:EditWatchlist listing all the pages I watchlist, even if I never use it other than to create a data backup every year or so); this might have GDPR-compliance aspects.
Would it be possible to create a special page listing all the pages I've subscribed to new topics for?
