We do not currently ship min/max (though we do ship an infinite bucket which is the max) in OTLP histograms. At this time, we cannot add them because we are waiting for a release of opentelemetry-proto (see open-telemetry/opentelemetry-proto#387). When we do add them, we will need to figure out the right semantics of what min and max will mean. See #3129 (comment)_ for some initial thoughts.
