There are no implications, since Ethereum is a public ledger where anyone can participate in validating transactions who have at least 32 ETH. For contrast, with bitcoin anyone can add a block who can produce a verifiable hash below the current difficulty target.

It gets muddy where with Ethereum where there are public companies like Coinbase who have to comply with certain laws as they are a financial entity running their own validators with coins from their depositors. Don't get me wrong there is an urgent need for regulatory clarity and not all regulations are bad.

So then is increased length of validation for non-compliant transactions the only tangible drawback?
