I like using Workers for smallish http services. The uptime, pricing, and latency are fantastic. I would never use them for anything complex as the vendor lock in is quite strong and the dev experience still needs to improve.

Containers on the edge with low cold starts, scalability, the same reliability as Workers, etc would be super cool. In part to avoid the lock in but also to be able to use other languages like Go (which Workers don't support natively).
