> As noted by Tomas in SOLR-10835, since the numeric FooPointField classes use SortedNumericDocValues,
the docvalues don't "dedup" when the same value exists multiple times for a single document
-- this is different from the numeric TrieFooField classes that use SortedSetDocValues - which
are by definition a _set_ -- so multiple instances of the same value are de-duplicated.
> This impacts things like the ExportWriter, as well as fields that {{useDocValuesAsStored="true"}}
if users have particular expecations when converting from Trie fields to Point fields.
