That’s what readwrite.com says. I think what the NSA says (or said; that is dated April 2023) is here: https://media.defense.gov/2022/Nov/10/2003112742/-1/-1/0/CSI...

I couldn’t find the word “suggest” or anything similar to it in that paper. They describe what they mean by “memory safety” and give examples of memoryxsafe languages (twice, both times the same list)
