A/B-Testing through load balancing

The docs recommend setting up A/B-Testing using CF Workers (https://developers.cloudflare.com/workers/examples/ab-testing/). My question is if workers are really necessary for that of if it also can be achieved by only using the load balancer? Our use case is that we want to do a canary rollout of our new checkout experience at first to 50% of our customers and a selection of our products and test how it performs. If it performs well we want to gradually roll it out to more customers and products.
