Hello @ivan-kyuchukov

That is not a mistake.

This contract include a decimal function.

    function decimals() public view virtual override returns (uint8) {
        return 18;
    }

If someone wants to change the decimal, the process is to override the decimals() function. We left a comment here, because devs coming from a 3.x version would be looking to customize that in the constructor → this message tells them that the upgrade is done elsewhere.

Maybe the documentation is confusing because it's in the constructor. We could move the part about decimals to the contract-level docs.
