I believe general purpose tool will atract people with general knowledge, so more people. Very specific dev will atract experts, so less people will engage to the work.
Local minima though, that larger group of people have already found the fastest/easiest/most intuitive way to build the everything tool. You've got a lot more prior art to be better than. If your goal is wide adoption and hype, that's not a great starting point unless you've found the next local minima.
