UDP doesn't implement:

- Reliable delivery

- Ordering

- Congestion control

- Flow control

...and a large list of RFCs that I'll never ever read.

If you are delivering a document (like a webpage or an API response), or transferring files, you want these things.

If you are doing real-time stuff, like video, voice, real-time games... and you just need the most recent information, that's where UDP shines.

I think the author is aware of that. I think it's more an easy way to 'udp-fy' existing tcp services and only update the client to use udp
