    Except the part where it didn’t imply that at all?

    That performance cost seems to be negligible in uBlock Origin and other popular ad blockers that have focused on optimization (uBO has an explainer wiki page), but there were probably other extensions not doing that well. It’s not hard to see a situation where multiple poorly-optimized extensions installed using the Web Request API could dramatically slow down Chrome, and the user would have no way of knowing the issue.
