Related question raised in #274 (comment)

Currently:

This metric SHOULD be specified with ExplicitBucketBoundaries of [ 0, 0.005, 0.01, 0.025, 0.05, 0.075, 0.1, 0.25, 0.5, 0.75, 1, 2.5, 5, 7.5, 10 ].

And the question is:

what is the point of having a boundary of 0 if we know the values we observe cannot be negative?
