Honestly, for my own stuff I only need one PoP to be close to my users. And I've avoided using Cloudflare because they're too far away.

More seriously, I think there's a distinction between "edge-style" and actual edge that's important here. Most of the services I've been involved in wouldn't benefit from any kind of edge placement: that's not the lowest hanging fruit for performance improvements. But that doesn't mean that the "workers" model wouldn't fit, and indeed I suspect that using a workers model would help folk architect their stuff in a form that is not only more performant, but also more amenable to edge placement.
