What if @grimoire type spells, and follow-lists were the same thing? Is not the ''main'' follow-list just ''all the things from this list of people'', which you can translate into a nak query thingy? and subsequently you can add specifiers on things, making lists distinct; the definition of the list, is the query. i.e. ''what type of list is this?'' "Oh, its a list that looks at the recipe-kinds of the people listed on these particular relays'' ''that is what that list is, how nice that i understand, and that we did not have to set up some committee to define all the possible list types, because we can express all possible list types via query/defining npub, kind and relay'' Its not nicely indexed, but the Clients would also know what to look for based on kind specifications in the query , and could also choose to modify them (like remove unrelated kinds).
