Getting people to use things requires communicating to them what the things is for, and how it is better than other alternatives, and how to use it to realize that benefit.
Therefore, devtool adoption requires messaging related to what the devtool is for, how the devtool is superior to other alternatives in the same space, and how to use the devtool to realize that superiority.
Actually having the tool is a start, but its not the ballgame if no one can understand what its for, why they should use it over other things that serve the same purpose, and how to use it.
