#5974 introduced the support for configuring HistogramFlavour/buckets per meter for OTLPMeterRegistry. This was done as part of a configuration that was supplied during the registry creation and does not allow overriding via APIs. This configuration does a full match of the meter name and requires the fully qualified meter name to be provided and this can get longer when we need to supply configuration to a family of meters.

Spring boot has a solution to address this issue by supporting the prefix and if there are more values the longest match wins. If users can supply a Function to be applied for determining these values also be an option to try out.
