Nah, there's a big difference between what and how much you're allowed to block in V2 vs V3 - the current status V2 adblock is way outside the range of V3's version.
I'd say V3 blockers can probably block at best 30% of what V2 can block. Which means it has to be selective. It essentially nuders the extension, making it worthless - an adblocker that only blocks some ads is not an adblocker at all. It's more of an ad restrictor, and in heavily monetized sites it might not even be that.
