How much would it hurt Ethereum if Etherscan lost all smart contract ABI's tomorrow?

I like building apps on web3 protocols. DevRel @ ENS Labs. gregskril.com

Some but Eth is so distributed at this point that others would quickly hit up the slack as an opportunity.

My guess is other block explorers would try to swoop in, maybe historical decoded txs need to be paid for. Would be a big hit to the ecosystem tho for sure.

I think the bigger problem would be going backwards though. We would effectively lose most decoded transaction data, no?
