The M7 core is for real time code, power and sleep management, and offloading small processes that would waste too much power waking up the main cores. It's not meant to be powerful, it's meant to be ultra low power.
I don't know why you'd expect it to be an A53 or A76 core. Those are much more complicated, power hungry, and are made redundant by the x64 cores.

I'm simply pointing out that Cortex-M and Cortex-A are grossly different. Read the thread again: many people here are confusing M and A cores: as if all ARM chips are the same or something.
