Wow thanks! It's pretty cool you noticed some of this stuff. :D It's partially that the big CDNs caught up, and partially that we have the luxury of not having to worry about a big legacy CDN. This iteration in particular has felt really right, but would have been infinitely hard to pull off if we were Fastly/Cloudflare. We are focusing a ton on how to make app servers fast, basically bringing some infrastructure tooling to "boring" server apps (which are my favorite). We definitely have plans for other PaaS providers. If you have requests I'd love to talk to you about it: kurt@fly.io
