That is not something which has factored into the conversation on our (Cloudflare's) end. The bigger issue is even as we make technical improvements, we very much don't want to create a separate Internet. The minute we begin adding, removing, or changing content when it comes through Warp those questions begin to be asked.
You also don't want to be in the business of determining which ads are "good" and which are "bad" and being tastemakers in any way, so probably a smart choice to stay out of the ad game.
A good add on though might be a way for people to run their own service on a Cloudflare worker that gets hit with each request to 1^4, which would allow them to run their own ad blocker.
