Hi @brandonc!

Just as an explanation for why you're seeing some radio silence here: this "intro" part of the docs largely belongs to the marketing folks rather than being a typical part of the documentation. What you proposed here seems reasonable to me but it's not typically my place to approve changes to this content. I'm not sure who is actually responsible for doing that.

With that said, this makes me wonder if it would be better to revise this text to be more "evergreen" by not mentioning a number at all. Of course that only exacerbates the "not clear who should approve it" situation, so probably better to save that for separate work rather than try to do it in this PR, but I'm mentioning it mainly because hopefully someone who is allowed to make that decision will see this PR and can consider it separately. :grinning:
