Are vintage dropouts a design flaw or hazard?

I was riding my Bianchi today. It has Gipiemme dropouts that look like this:

As I was standing and hammering up a hill in what was probably a too-high gear, my wheel moved in the dropout. I have closed-cam Crampy quick-releases. I guess I just didn't have it on tight enough.

In any case, the wheel immediately locked on the frame, and down I went. Fortunately, due to my overall suckiness, I was going about Garmin-pause speed, so nothing bruised except my ego, and maybe my knee and hip. (It was my first significant fall since breaking my ankle 5 years ago, so I was pleasantly surprised by the outcome).

Was this dropout (from 1986 in my case) a design flaw?

I looked on my 2014 steel bike and the dropouts for the rear wheel go down, not forward, so presumably the risk of the wheel moving in the frame is substantially less.
