here's a little test on real data const queryDuplicates = L.esri.query({url:'https://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/Neighborhoods_pdx/FeatureServer/0/query'})
queryDuplicates.where("1=1").fields('NAME')
queryDuplicates.run(function(error, featureCollection, response){
console.log('Duplicates query (anticipate 130)', 'Found ' + featureCollection.features.length + ' features');
})
const queryDistinct = L.esri.query({url:'https://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/Neighborhoods_pdx/FeatureServer/0/query'})
queryDistinct.where("1=1").fields('NAME')
.distinct()
queryDistinct.run(function(error, featureCollection, response){
console.log('Distinct query (anticipate 126)', 'Found ' + featureCollection.features.length + ' features')

hello @jgravois here is the PR discussed on #1026 - the test is a work in progress, however the method itself appears serviceable on real data.
