Naftush, the side effect of the freezer is that hundreds of boys start shidduchim at the same time, but it’s certainly not the intention, and I don’t know that it has any effect on the overall picture.
Yes, the OP picked Tu B’shvat, when these boys start dating, to discuss whether they are properly prepared, but there’s no real connection.
Maybe there are ways in which the shidduch process is “engineered” that we can discuss, but the freezer isn’t a great example.
