It also greatly feels like they intentionally evolved the highborne to a more night elven version, so as to make highborne clearly a High/Blood elf thing, and their equivalent on the night elf side to be nightborne.
I probably suspect they will either leave the shen'drelar as unique relics, but get away with it cos their numbers are so tiny, or just have them transform to nightborne via the nightwell, or have them join the high elves and turn into high elves via the sunwell.
Making it simple for players hence forth, Highborne = high/blood elf thing, Nightborne = night elf thing. Highborne night elves all became Nightborne in the end and this is how you distinguish them from normal night elves.
