BlockTube
By now it allows to block (remove) other things: Auto-generated playlists, Explore page, Shorts, Movies and a few other things.
I mostly use it to block content about stuff I don't want to get spoiled on. It supports regex so it's fairly easy for me to very rarely see anything that would diminish my experience from a specific piece of media (assuming I don't forget to do it in the first place...).
Ignoring the fact that they were clearly talking in orders of magnitude, it was 8MB for a very long time and only recently got increased to 25.
