Sass: Including mixing library (Compass, Bourbon, etc.)?

Seems not to be the most popular subject in the forum, therefore I wanted to know your advices about including or not including a sass mixin library like Compass or Bourbon in a Ionic2 project?

Actually I ask my self this because I add to implement a linear gradient and I didn’t wanted to reinvent the wheel, that’s why I included Bourbon (in comparison to Compass, seems to be lighter).

So, any thought? Good or bad? Or absolutely no need to done (maybe Ionic provide such mixins, I didn’t found it but maybe)?

Thx in advance for your help.
