FYI: @openzeppelin/contracts-ethereum-package 2.2.3 is equivalent of OpenZeppelin Contracts 2.2 + GSN support.
@PaulRBerg raised in Telegram that upon switching from OpenZeppelin Contracts to @openzeppelin/contracts-ethereum-package their tests failed due to lack of revert reasons.
Revert reasons were added to OpenZeppelin Contracts 2.3 (along with ERC777 implementation).
