Hm. This internal stress issue you describe might be a thing, but I'm pretty sure bubbles exsolving during freezing is also a thing. Most of the times I tried and failed to make clear ice there were obvious bubble exsolution trails.
Just put a double walled insulated cup in the freezer. The internal stress explanation accounts for 98% of the result when you think through how the crystal growth happened.
Also notice the radial pattern that the internal fractures take. This is inconsistent with bubbles and perfectly consistent with internal stress due to expansion pressure.

In that photo I see a few gas bubbles, but it is dominated by radial expansion fractures and cloudy high pressure ice in the center. That ice will crack when put in water. Clear ice does not crack.
