I don't understand the relevance of this.

In my view, we would prefer miners to invest in hardware just a mere
2016 blocks away from the halving. Instead, they've made them too soon.
Assuming that miners are already located in low-power-cost areas, the
difficulty will be quickly rising to compensate for "state of the art
power efficiency".

So it will have canceled out by July.

If anything, the more efficient miners become today, the bigger our
potential problem in July, because chip-manufacturers may have used up
all of the easy efficiency-increasing moves, such that investments do
not take place in June.
