Indeed, talkdown, those days have 'gone' - both NoD and I being ex mil were well used to 'winging it' and (nearly always) quite capable of doing so safely. All controllers need to NB NoD's info on any change in flap setting in order to accomodate a 'changed' landing roll.
HD - all the examples you gave were, I think, as NoD says, where the crew have briefed and planned options which is quite different to catching a curved ball at 500' and I'm sure you understand that 'slackening' a landing roll (ie 'roll to the end') is far easier than 'tightening' it. What helps is, as some airfields do, to publish 'preferred' exits for different categories in the plates.
