Is it sensible to kill any footer-hanging block containing "cookies", "use" and a button/link "accept"? As a measure to reduce site-specific filters.
Is there a better system for collecting and storing filters, rather than by-site filters in git? Look at SponsorBlock - I think they have self-moderated system with users submitting advertising blocks of YouTube videos. This one can have the same, but for per-site selector, and in some DB, probably.
