I believe Elasticsearch is a trademark.

If it really does work this way, then we're all doomed.

If its use is so widespread, then it's probably no longer a trademark, in that context at least.

A trademark does not forbid people from using a name, it only restricts how it can be used in marketing. I do not see how that would be applicable here.

Are HTTP headers important or even relevant at all for branding trademark purposes?

Such a concern seems utterly ridiculous.
