https://docs.soliditylang.org/en/latest/080-breaking-changes.html says:

Arithmetic operations revert on underflow and overflow. You can use unchecked { ... } to use the previous wrapping behaviour.

However OpenZeppelin are keeping it for reasons explained here:

OpenZeppelin/openzeppelin-contracts#2465

It would be helpful to update this blog to reflect that.
