> LUCENE-10325 added a new {{getTopDims}} API, allowing users to specify the
> number of "top" dimensions they want. The default implementation just
> delegates to {{getAllDims}} and returns the number of top dims requested, but
> some Facets sub-classes can do this more optimally. LUCENE-10325 demonstrated
> this in {{SortedSetDocValueFacetCounts}}, but we can take it further. There's
> at least some opportunity to do better in:
> * {{ConcurrentSortedSetDocValuesFacetCounts}}
> * {{FastTaxonomyFacetCounts}}
> * {{TaxonomyFacetSumFloatAssociations}}
> * {{TaxonomyFacetSumIntAssociations}}
