Though, maybe not. Opening a new context still wants some kind of summary opener. If your message is short, you might just say it. But if your message is even slightly long, you probably start with a heads up what the overall gist and point will be. "I have a question." rather than just the question. Or "Accounting just told us we have to..." and then all the stuff Accounting said and what you have do do about it. Are those openers the most significant bit or the filler? Definitely "I'm OK" or "You have to turn in your laptop." is absolutely the wrong way to start. It's even like going out of your way to find the worst possible choice out of all the bits in a particular situation. Random order would be better. So maybe it's not wrong to start with the most important part, but the definition of most important part is apparently up for grabs.
