Our biggest issue with Oracle BPEL is that it is a monolith. Because it's a monolith, everybody tries to consume its services in a shared infrastructure. Because of this, some companies are trying to migrate to a microservice architecture. We use API gateways to get around these issues. If you want an orchestrator with BPEL and you have an API gateway with a layer of services, you can combine both technologies and try to get the best of both worlds. In the next release, I would like to see REST improved and new technologies for microservices. I'd like to see more containers for separating containers.
