Is it prohibited to include `X-Elastic-Product: Elasticsearch` in the output of your server if the user instructs the server to do so? :)
Such a concern seems utterly ridiculous.

my guess is because it's "X-Elastic-Product" you'd be falsely "saying" your product is made by Elastic, the company so they could sue over it.
