Looks great and much better than my piecemeal efforts, although I recommend linking to a specific commit of all.txt so you aren't opening up your browser's ublock origin filter list to arbitrary remote control. Like:
As the author of the filter, I strongly agree with you. However, I believe it would be too tedious for most people to update the filter "by hand". I think I'm going to add this important security information in the README.
