I’ll close with a more real world example. Decades ago my older brother asked me if it bothered me that our father never said “I love you” to us. With hardly a beat I said no, it didn’t bother me at all. I replied it didn’t bother me because I knew without doubt Dad loved us. His love was there in his words and actions. Whenever he called me up just to talk about hockey, cars or whatever. Whenever he asked me to do something with him. Whenever we did something together, Whenever he might ask my opinion. Whenever he teased me or we laughed together. And whenever I needed help he was wordlessly there. Dad’s love was there on display with everything he did and I didn’t need to be constantly reassured about it.
My Mom and my experiences were the same.
However, I really don't think some people requiring more emotional support than others is a modern phenomenon.
