All remaining functions not mentioned in this section do _not_ work with native
histograms. Histogram elements in the input vector are silently ignored. (TODO:
Make sure this is the case, rather than treating histogram samples as floats
with value 0.) For `<aggregation>_over_time()` functions not mentioned before,
native histogram samples are removed from the input range vector. In case any
series contains a mix of float samples and histogram samples within the range,
the removal of histograms is flagged by an info-level annotation.
