My guess is that 3rd party apps have reached a user threshold where they pose a potential future risk of pulling the rug out from under Reddit enough to give some non-negligible traction to an alternative. After all, once you've got the app installed, the back end server can be replaced with something else and you can find ways to streamline new user account creation where needed especially if they are paying customers, even offering to reserve existing Reddit usernames on other platforms.
If a Reddit IPO is coming, then this could simply be a form of de-risking. It's a double edged blade, because higher quality 3rd party apps may increase the platform's value while you're on their good side, but rub 3rd party app developers the wrong way and they might start getting clever ideas. A short notification period may reduce the chance of clever ideas reaching manifestation.
