The paper discusses how source address token might be used in tracking and thus online advertising services, Google's business.
The online tracking and advertising industry and companies selling to that industry such as Google believe IP addresses, when combined with other information, tell something valuable about consumers.
Perhaps users of the "modern web browsers" cannot or will not manually control generation or storage of source address tokens. Hence the need for papers like this one, pleading with the organisations controlling the browsers to change the software. That software is of course written by employees of companies and parents of companies that are paid directly or indirectly from sales of online advertising services.
Probably the folks creating these protocols never thought about the implications of the design on online advertising services. However, from the perspective of people selling internet advertising services, the association/non-association of IP addresses with public keys seems like it might be significant, regardless of its intended purpose to the protocol designers. People buying those online ad services are likely to understand the potential value of IP address information, e.g., they might think it tells them something about geo-location. If so, they might also see the added value in the combination of IP address with a unique identifier.
