This is API that ABP can use. But with the new API the rules list will be limited to 30 000 rules vs. for example 42 000 EasyList is using, and an update to the rules will require a full update of the plugin.

This means they anticipate Google to target the Acceptable Ads program.
Originally I thought 30,000 rules wouldn't be enough to cover things, but according to this research, only a couple hundred rules are enough to block >90% of the ads: https://brave.com/the-mounting-cost-of-stale-ad-blocking-rul...
So maybe there's another limiting aspect of the declarativeNetRequest API I don't know of.
(register 50k domains, use 50k different subpath/subdomains and mix content+ads on something like youtube where you cant wholesale block youtube, etc)
Thats just false. Every adblocker using webrequest will be affected, including ABP.
