Developer would have to release a new version every day because currently, that’s the only way to update the filters. This is very time-consuming, and the approval process for the add-on also takes time, which means the filters will be outdated on the day the add-on is released in the store. If Google doesn't backtrack on the manifest v2 block, I’m not sure if uBlock for Chrome won’t be completely abandoned.
Now, instead of focusing on the development of the program, the developer will waste time and resources on releasing pointless new versions just to update the filters, because otherwise, users will be dissatisfied.
