Your proposal is for each facet of content you wish to block be an Addon/Extension/Plugin which is completely unnecessary. Today uBlock Origin and other products perfectly handle multiple lists pulled from different maintainers simultaneously.
There is no one central block list, out of the box uBlock Origin uses something like 9 or 10 different lists and the interface has ~50 to choose from. It also has the ability for you to import your own lists form custom sources and to maintain your own.
