It would also be amazing to see some larger txs, and put to good use. If the tx size is over 100kb, the person takes up half the sidewalk! :D
Look, there is a project called Matter (www.mttr.app) that has this main objective, to use op_return space to send pictures, books and long text like blogs. It is in alpha.
Looks pretty good. Can't all the post chunks be in the same tx though? Why create multiple txs when you can just create multiple OP_RETURN outputs? It's more efficient.
Having a limit at all seems counterintuitive, now that projects are finding ways around it (inefficiently). I think BCH could enable multiple OP_RETURN outputs without a hard fork.
