From my experience with LLMs, it matches your description of "corpo-speak". I think it is the right balance of politeness. The result is usually rather simple, and when it is not, that's because it wants me to add extra information, which is often a good idea, not because of too much politeness. It is not at all like you say in the end, way more boring and that's the point. But out of curiosity, I asked ChatGPT for some appropriate formula for a use case like yours and I got "Sounds good to me! I accept your suggestion—let's move forward with it." Of course, there is some formalism here, in day-to-day communication with people you know, I found it to become less formal over the years. "ok" is fine now when it wasn't before. I think because test-based instant messaging is now commonplace.
