Even more egregious are those stupid "RemindMe!" bots which in a very ham-fisted way create noise for everyone except the one person triggering the bot (ironically, a 3rd party app would be way better suited at implementing this specific feature)
People have wanted schedulers and the ability to subscribe fr updates posts for years. Thankfully, RES has had that for almost a decade now.
Don't think Reddit even acknowledged that feature request, compared to others they said "we're working on it" some 7 years ago. Closest they got is how the subscriber plan lets you highlight new comments in a post (something RES also had, but reddit made them remove it), but you still can't notify yourself to when new comments occur.
Just another example of not considering the user. Pretty sure filtering subreddits from r/all was the last user-centric feature they made. And that was more made out of spite of the political shitshow that was 2016/7 as opposed to thinking about the users.
