Thank you for the context and this is what I was getting at - if you really want to dig in on things like KV, D1 and DO you will see occasional mentions of regions (I'd really call it geography) to add context on things like "KV is eventually consistent, instant in the pop where the write takes place but takes X ms to propagate everywhere". For many (most?) applications it doesn't really matter, I get the sense for these you clearly document these things so people understand the more-or-less inescapable fundamental reasons why things are what they are. As other commenters have noted "there is no free lunch" when it comes to things like the physics of getting data from a pop in Tokyo to Chicago but Cloudflare does a good job and making it happen more-or-less invisible.
