It establishes that operating systems have the necessary infrastructure to reveal information about their users in a standardized way to other systems on the internet.

Once that is established, it is easier for politicians to push for newer laws that add more features to reveal even more information. Politicians can propose any unrealistic law they want. But it is much easier for them, to convince a necessary majority, when there is technical infrastructure already in place. "We are already doing X, why don't we just also do Y?". Or: "Country A has already X, why don't we also do X?"

This forewarning is underestimated. Russia had begun it's path to Internet censorship through "think of the children" and to fight piracy. Started off as simple DNS and IP blocks, mandatory for all B2C ISPs. Now every egress international connection is being analyzed by DPI, VPNs, SSH are broken: the traffic inspection and interception (TCP RST among other things) has to be circumvented. Major messenger apps are blocked: WhatsApp, Telegram (intermittent connectivity), Viber etc. to force people to use the unencrypted local app (an FB Messenger equivalent, called "Max" by VK).

There are now plans to expand the traffic analysis systems' aggregate bandwidth to nearly 1 petabits/s (sic) by 2030 with the expected total budget of 59B Roubles (470M USD).
