Indeed.
Perhaps a hobbyist would code “MV2-capable” MV3 adblocker for the fun of it, forking UBO or something, as a proof-of-concept. How much time would anyone spend on its development and who would install it when the max runway’s a few days, weeks, or months?
It seems someone's already done it. It requires some extra setup, but I managed to get it working on my machine.
