Yep. Too much power for some bike, or some rider. Even then, a bike always can be improved, and a rider getting better. IMO, that is the purpose of building, and riding.
I had a goal to build a 40 hp bike using only bicycle components. I don’t know if I will ever make it, but I am now at 25 kw sub 100 lbs and the bike would like more. The fact is, it is getting harder and more expansive with every bit of extra power. So I am stucked there for now. The bike I am building now will have less power, only I had to build something to clear some of the components that are crowding my shop.
