What’s the fundamental difference (and thus main benefit ?) between measure:accuracy, accuracy:measure or est_height ? They’re all telling that the given height is an estimate within an undisclosed interval of confidence?

I wonder if it’s not.better to accept that *any* measure is an estimate, and let mappers improve the accuracy, just like the drawing of a highway can be a poor or a great estimate, which improves over time as imagery or traces permit improvement.

Even if the imagery is of great precision, it’s not a guarantee of.accuracy, as the mapper might be in a hurry or might not particularly care for accuracy, and leave to its successors to improve it.
