Speaking from experience, it sells better to bring along special soft skills in the package, than yet another technology stack.

Too many coders, generalists or not, cannot engange properly talking to something that isn't a computer.

Those that manage to merge coding skills, with UI/UX, marketing, understanding the customer point of view, already have an upper hand.

Yes, you need soft skills too. But that doesn't mean you shouldn't specialize in something. That doesn't have to be a tech stack either, in fact it's the last thing I would suggest.
