thanks for providing this brilliant map service. I'd like to use it in a third-party application (a website), in accordance with the terms of use. I am sorry if this has been asked before, I tried to check the last couple months of the mailing list, but couldn't find anything related.

For privacy reasons, the website uses the no-referrer policy. While I think sharing a referrer with Wikimedia is alright, my website allows browsing OSM data, including links to the websites set in OSM, and I don't trust these websites with a referrer. Unfortunately, the referrer policy does not allow fine-grained configuration, it's a global on/off switch. Changing the user agent in a browser is considered a hack, and while it might work, it can break other third-party tools and could break with every browser update or when using an uncommon browser.

So I was wondering if you would consider a third method of authorization, like a query parameter that can be added to the url like `?referrer=example.com&contact=mail@example.com`? I think this could help people to use your service in accordance to the terms of use.

Thanks in advance,

Robin
