It should be OPTIONAL to let either Spring-Cloud-Gateway or downstream application to handle CORS preflight request.

This was a change in the Spring Framework. Although the comment says "does not change how Spring MVC or WebFlux process CORS request" it does appear to change the code path. I think you need to open this with Spring Framework team. It looks like a non bwc change.
