I know that the latest Solidity supports error messages in require/revert (
Are there any clients that can get this message? Will I be able to see it if I execute the transaction in Parity, or Truffle, or Remix? Will it be visible on Etherscan?
EDIT: a similar question has been asked before (Custom error message in require() not showing up?). That one was about web3 not displaying the message. I know web3 doesn't support it yet, my question was about which other clients (Parity, Remix, or, maybe, just plain RPC) support it, so I believe it's not a duplicate.
