Hi Russ,
Can you say more about the compatibility implications for such a change?
AFAIU, things shouldn't "break" for users or throw errors behind the
scenes, correct?
thanks,
Mike

K-anonymity enforcement has long been a part of the Protected Audience
API’s plan for improving user privacy by limiting ads that can win
Protected Audience auctions to those ads that are k-anonymous. The
k-anonymity enforcement feature limits the ability of advertisers to
target specific users by requiring each ad be shown to a minimum
number of users. This enforcement will initially apply to up to 20% of
unlabeled traffic only, meaning the groups that are part of
Chrome-facilitated testing
<https://developers.google.com/privacy-sandbox/setup/web/chrome-facilitated-testing>for
third-party cookie deprecation will not be enforced for k-anonymity
during the testing period. After the testing period, enforcement will
apply to all traffic (see timeline details at
https://developers.google.com/privacy-sandbox/relevance/protected-audience-api/k-anonymity
<https://developers.google.com/privacy-sandbox/relevance/protected-audience-api/k-anonymity>).
