When cleared to land your clearance limit is the runway, you are not cleared for the missed, the pattern or any combination thereof. If you need to go around a new clearance must be given
Is that one person's personal opinion? Or is this information published somewhere?
Normally a clearance to land automatically assumes a go-around may be necessary for safety reasons. For example a hard bounced landing resulting in a go-around or windshear or a late go-around due excessive crosswind. In those examples there is no time for instance to politely request approval for a go-around from the bounce!
