I’m not really Indian myself (didn’t grow up in the culture/my mother’s tribe) so I don’t think it’s my place to say whether it’s a good idea to include it in modern American Indian cuisine.

I will say that other oppressed groups have successfully integrated foods that came out of hardship into their cuisines - think matzah and components of Soul Food.

I wouldn't quite put matzah in the same boat as "food that came out of hardship", as the exodus is a founding myth & even if partially based on true events these events happened about 3500 years ago. Furthermore Jews today don't consider it as a tragedy (unlike e.g. the more recent and much more historical events commemorated by Tisha B'av).

I read an article recently about Native American cuisine, and from what I gathered from that, Native Americans themselves are incredibly divided as to whether or not to include frybread in these kind of restaurants for that reason.
