Yeah. Interesting to think if there are ways to get around that problem.

At a first flance, perhaps a uBlockOrigin-style control pane with per-domain toggle, so that for example you can send the info only when browsing a specific domain (let’s say, a news site; that’d be interesting to find discussion in Lemmy of). This would also prevent the issue of sending URLs that are not internet-wide (eg.: are on a localnet resolver, or an intranet).

As well as the abiity with an option send the request through a relay or proxy, to remove IP origin information that can be used to build the profile.
