I’ve mentioned multiple times that Luke as solo maintainer is not ideal and would be great if more developers joined the review process. Developers like yourself are basically saying they know best and ignore valid criticism, this is why node runners are opting to run knots in droves. Your argument that a miner api would pop shows that the OP_RETURN limit is doing its job. All miners would have to opt into this API and then the hashers will decide where to point their hash and can boycott miners who accept spam transactions. Forcing preferences are bound to fail.
