Even if that was implemented, it's quite a messy thing. For one, now the 3rdparty apps are a separate charge from being charged for reddit. When something breaks, and makes your paid for app unusable to access reddit, who do you blame? Reddit, or the app developer? There's also now the matter of all requests to reddit being made via 3rdparty apps requiring an API key that improves reddits tracking. No more anonymous access via 3rdparty apps, which at least for some of them was a selling feature.

It might be possible, but it will still increase the friction to using 3rdparty clients, and that's probably the whole point anyhow.

> It's too early to know whether this will be a realistic option. From what I've seen, Reddit may be turning developer signups into a manual process where each user would need to message them and get approval. Also it's likely they'd crack down on this if they knew it was happening.
