"... now hundreds of blockchains, coins, etc that can post arbitrary plain and crypt text in their data field alongside the transactions ..." Cypherpunks is a list for discussing the politics of networked cryptography aka ' cryptoanarchy '. Coderpunks is the list for drilling down on the technologies associated with that.  APster was working fine years before 2008 and the first blockchain. The charges against c-punks, Jim, Carl and myself testify to that. And APster will be working fine when Gramps, Batshit and Karl garbage are just a bad memory, I promise you.
