Chrome (at least?) solves this via Text Fragments[0] which are a pure client side thing and requires no server or site support.

This URI for example:

https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/...

Links to an instance of "The Referer" narrowed down via a start prefix ("downgrade:") and end suffix ("to origins").

These are used across Google I believe so many have probably seen them.
