WK teaches the readings れつ and れ for the kanji 列 (“Let’s (れつ) Ray! (れ).”)
My question is: is the れ reading important enough to be taught at all?
My (admittedly limited) searches have found only a couple of ateji in which it’s read as れ.
虎列剌 Cholera
列寧 Lenin 
So I thought I’d check with the more experienced folk here before bothering the WK team about it.
Not sure if it helps
