My core thing is that the OS should by default be tailored to give a good experience for the most common user. The vast overwhelming majority of users will never need profiling, and should not pay the cost. As a developer myself, I find it totally reasonable and expected that I need to spend time and effort configuring my system to be a development environment. I'm doing something unusual and it requires extra tools. My grandma does not need a development environment. Even on arch Linux, the number of developers relative to the number of normal users has to be vanishingly small. Optimizing for the rarest of rare use cases doesn't seem like a great choice to me.
