The statement and PR are different from what you're suggesting: if the tx is valid, then the OP_RETURN size should not be capped at an arbitrarily low limit by default, because OP_RETURN was made for storing data and can be pruned by nodes that don't care.
Why bitcoin? Because everything else has worse guarantees of persistence and integrity. Proof of Work required.
