Sav mentioned previously in the thread that the release version of the game may prune clearly half baked/unfinished characters, with an option to enable them in the settings like Skyrim's "Cutting Room Floor" mod.
Elf boy may or may not fall into that category. Kinda subjective, but I turn him off every playthrough and I'm not sure that anyone would notice he's gone.
Kitsune Scouts I think are fine, tbh. Assuming you're talking about Hinata/Kiri/Yuzu, they seem to mainly be introduction/setup to the Kitsune Den.
