One thing I dislike regards to SSE, which is not its fault but probably a side effect of the perceived simplicity: lots of developers do not actually use proper implementations and instead just parse the data chunks with regex, or something of the sorts! This is bad because SSE, for example, supports comments (": text") in streams, which most of those hand-rolled implementations don't support. For example, my friend used an LLM proxy that sends keepalive/queue data as SSE comments (just for debugging mainly), but it didn't work for Gemini, because someone at Google decided to parse SSE with a regex: https://github.com/google-gemini/generative-ai-js/blob/main/src/requests/stream-reader.ts#L28 https://github.com/google-gemini/generative-ai-js/blob/main/... (and yes, if the regex doesn't match the complete line, the library will just throw an error)
