Mostly yes, and I think the OP is well-written.

But note that in some cases, eg https://en.wikipedia.org/wiki/Tajik_alphabet#Samples point number 2 won't be accurate. I'm not the best reader of Tajik written in (Perso-)Arabic script, but I don't believe "ال" appears in the samples there. (It does appear in the word "ALphabet" in the opening paragraph!)

And also Aramaic dialects like Syriac

Syriac script looks completely different to Arabic but has the same issues when rendered
