I can see how early ice could suffer such a breakdown, but once the lake has a foot of ice, it would be pretty surprising to see a spontaneous formation like what is described.
Now gas holes do happen, though few and far between.

I’ve witnessed them growing out of 10 inch ice. I wonder if I never noticed them and they’ve been around. I have driven on many lakes and never came across any significant slush ice fishing except in late spring when I always walked on.
Here is a link to the only paper ever written on these lake stars.
