I am Italian and was taught cursive in elementary school and I can barely remember upper case cursive letters[0] thirty years later.

In my experience, most people of my generation have generally forgot and usually just write "lower case letters but big" or block letters.

So yeah, I don't think there's anything inherently chinese about forgetting writing things you don't use.
