Have been using my new M1Pro 14'' (base model) for a week or so now and besides the memory leak issue (which I also have) I saw that kernel_task uses 575 threads and is quite often at the top of CPU consumption (in the screenshot the mac is pretty much idle with a few programs open in the background, temperature is about 48-50 Celcius / 117-120 Fahrenheit on the cores). I compared this to my M1 Air, also on Monterrey, that does not have this issue, although it seems like the Air did not report "kernel_task" in the activity monitor at all.

For those who also have the new M1Pros - is this normal behavior or is there something wrong with kernel_task?

Mine has 545 and I'm on M1, not Pro. I think this is pretty normal especially when your Mac is plugged in.

It's okay, kernel_task is macOS's kernel — the core of an operating system that does memory management, networking, process scheduling and much more. If the machine is mostly idle, it only makes sense that the kernel itself is what consumes most energy.

the Air did not report "kernel_task" in the activity monitor at all
You probably have Activity Monitor set to "My processes" on the Air, and "All processes" on the Pro.
