Chrome declarativeNetRequest API considerations

During this lockdown period, I've worked a lot on browser extension. I like the idea to add features to chrome opera and firefox, but sometimes this can become tricky because javascript can't do all things that an app can reuqire.

In particular, I've looked at the declarativeNetRequest API that seems to be a nice way to block ads and trackers or net requests in a performant way that will not impact on page rendering while under the hood requests are blocked. The only lack is about defined rules update that will have a limit of 30.000 max possible rules and that are not simply updatable. I've done some tests with it and I'm not satisfied at all, I hope that the API will be improved in future.

Does anyone have eperience with this chrome API? Can you share your knowledge about it?
