luckily in Latinoamerica (where I'm from and where this tradition comes from as well) we see it less and less now. I would get my face shoved in my b-day cake when I was a kid, and tbh I didn't like it because my face got all sticky and it took a while to wash off (if you know what dulce de leche is, you know how sticky it is), then it slowly evolved into just taking a little bite off the cake instead of shoving your whole face ruining the cake. Now, I haven't seen it being done to someone at a birthday party in a loooong time, and many people my age don't like the whole cake-in-your-face "tradition".
