1) As nostr:npub1zsyt45zfh2u28zuhvp66lljp8s6jrwlw7ckvfn34255e7jt37t9qx0xwsm points out, it's disingenuous to point out that there are "hardly any" OP_RETURNs in the chain because the filters they're getting rid of are actually doing their job.
2) This "update" does nothing to address the root problem, which is using other schemes to stuff data into the chain.
3) Finally, the phrasing "we hope" has REPEATEDLY been used to preface reasoning. Bitcoin is not something you leave to hope.
4) Unlimited OP_RETURN data storage is an invite to all other $hitcoin chains and VCs to pivot into Bitcoin with affinity scams with "bitcoin" in their name.
Activity on the Ethereum and Solana $hitcoin factories will begin to migrate to the Bitcoin Network. This is hardly nothing. Bitcoin Core 30.0 , weakens Bitcoin, and changes Bitcoin's direction away from becoming "perfect money".
