Progressively as we move all the things to Webpack (see request #13714 and request #13299) we depend less and less on Gulp. Our main remaining usage is just to build all the components so it basically just search in the source tree all the components and exec "npm install" and "npm run build".
It looks like tools like Lerna [0] can do the same with some nice additions and less configuration.

I would like to start experimenting with it to see how it goes in our stack.
