According to Tomcat implementation, HTTP response splitting is not possible via HTTP Header injection. Other implementations may be vulnerable but that would be a vulnerability on those implementations.

So what's the conclusion here? Should this PR be merged or dropped?

I think the conclusion was to not add this to the default Response Splitting query but to create a new, opt-in Response Splitting query with those extra sinks so that customers can use them if needed.
