Hi folks,
Just to let you know, the Bower package manager tool has been put into maintenance mode officially:
bower/bower@0bd318d
The related issues was closed on the Bower project discussion list:
bower/bower#2298
The templates ships with Bower configuration and implicit dependency (as precaution the dependencies are bundled with template)
If you start some serious discussion on how to migrate templates to not use Bower and move to NPM/Yarn/Webpack, I'd gladly help.
