How could I do something like flatMapValues to a map? All that currently exists is mapValues... My use case is a json hierarchy that needs to be flattened into a Map<String, Map<String, JsonElement>>. It's something like { "level1": { "ns": { "s1": "", "s2": "" } } }, and needs to be [level1 = [ ns.s1 = "", ns.s2 = ""]]. And it's using Gson's JsonObject, etc...

might help to figure out exactly what kind of transform you’re looking for first

type-wise I mean

In the current mapValues, I can only generate one value per entry, but I would like to be able to generate multiple values per entry and flatten the result into one map (by concatenating the 2nd and 3rd level keys).
