I would also argue that focusing on developers too much is actually a loss for users. Developer productivity above all is how we've ended up with resource hogs like Chrome and Electron as well as never-ending erosion of customizability in software as well as the user's level of control and privacy.

It's critical to have a great developer story yes, but to make a stellar platform that needs to be balanced with a great user story, and that means developers might not always get everything they want down to the letter.
