I haven't used this bean before but after reading the docs and checking the code, this makes sense also from a security standpoint to get rid of all the forward headers and stop attackers injecting some malicious code there.

Same here, never used it before. But, just to be on the cautious side: can we add an "@ConditionalOnProperty" with a property that is set by default to false? That way those who want to use this can, and those who are unaware are not getting something they didn't order.
Talking of unaware: could we add some documentation to explain what this is for and why people would want it? Just to beef up the documentation (or at least a note that we need to explain later).
Other than that: good.
