> Speaking from experience, if you only need rudimentary L7 load balancing, then Cloudflare Workers is as good as it gets.

What would you do in Workers that you couldn't do with Load Balancing? LB handles origin health, can do traffic steering, session affinity etc included. With Workers, you'd need to take care of all that.

I see a point if the Workers do some lifting / caching / transforming etc before passing on the requests, but as a simple load balancer, the actual Load Balancing service seems a better fit.

You're right: Workers are not a generic L7 load balancer, but of course plenty useful for the other stuff you point out (for ex, transformations and caching).
