> I’ve seen other examples where customers guess at new APIs they hope that S3 will launch, and have scripts that run in the background probing them for years! When we launch new features that introduce new REST verbs, we typically have a dashboard to report the call frequency of requests to it, and it’s often the case that the team is surprised that the dashboard starts posting traffic as soon as it’s up, even before the feature launches, and they discover that it’s exactly these customer probes, guessing at a new feature.

This surprises me; has anyone done something similar and benefitted from it? It's the sort of thing where I feel like you'd maybe get a result 1% of the time if that, and then only years later when everyone has moved on from the problem they were facing at the time...
