I wouldn't even compare it to a tool. People frequently "build their own house" where they sub out 75% of the skilled labor and act as a General Contractor/glorified gopher.

And you won't get purity tests from the layperson: in the end, you're responsible for the build quality so if you tirelessly labor/oversee those teams you're considered capable; if it ends sub-par, then you're a stooge.
