Yeah, and you can also have multiple loopback interfaces in the 127.0.0.0/8 range if you want, no reason why you can only have one. That said, enough stuff out there assumes localhost = 127.0.0.1 = loopback interface that I wouldn't want to make my life complicated by breaking the convention.

Also, that comment was already a bit muc, and I opted to simplify a bit.
