Even though the Desert Princess face covering item is in the game, I doubt they would ever add hijabs. There is the whole political aspect about it as well as women's rights aspect. I am not saying nor believe that all women who wear them are forced, but they do exist.
On top of it, you have the whole cultural appropriation issue that always shows up and someone is going to get upset and take something too personally. I mean some people take offense to Aladdin which is a fictional story meant to capture the general Eastern Trade World.
Unlike turbans for example, Hijabs are typically not worn by people of multiple backgrounds. Other backgrounds have other styles headcoverings for women that are used. And although it can be tricky to tell what faith a woman has by their headcovering, it usually can be done if you know about them.
Do I think Hijabs should be added? Yes if they are still interested in adding clothes and adding cultural clothing. If they do it though, they need to have other styles of head coverings released at the same time under the idea of Cultural Clothing. It would be more acceptable plus it gives women of other backgrounds more options if they want a more unique personalized representation. Do I think it is a bad thing if they don't add Hijabs? Nope.
I am not sure if women who wear headcoverings all the time would want to in game as well. I must say the clothing is pretty numerous already... Maybe a way to remedy it is to have more sets of clothing like they did with the Festivale suite and zombie outfit. I mean mix matching is fun, but it does make it more complicated and eat up your storage when we have crafting materials to do that for us lol.
