* This extension is much less likely to consume all of my JavaScript resources when it malfunctions
* I, as the end user, can install this extension without fear that arbitrary code execution of code sourced from the web means the extension creator can change the extension to harvest my data later without anything changing in the Chrome Web Store to indicate this has happened
The bugs need to be fixed, but the benefits are for end users not developers.
Those benefits are like saying a benefit of having a flat tire is that you're way less likely to get a speeding ticket while you do. Or even better, like the benefits of the Sun going out that https://what-if.xkcd.com/49/ lists.
It's about tradeoffs. From where I sit (not running an ad blocker, but yes running several extensions on a corporate machine), the benefits outweigh the costs because while currently corporate IT has to allow-list every extension one-by-one, Mv3 allows them to have a policy where they trust the Chrome Web Store and allow us to install extensions as long as they don't demand XYZ permissions.
