After evaluating several Icon Libraries we've decided to go with Phosphor. The main reasons are:

• It uses a tone that is neutral enough to ship on a UI that can serve projects of any kind.
• It has more than 7.400 icons so far to choose from. It means that in the future it'll allow any contrib to extend the Navigation by providing a selector and there will be enough options.
• It has several weights and styles (like filled or duotone), which is a huge plus customization wise.
• It's licensed under MIT.
• The library is really balanced and well worked (as there are no bigger or smaller icons, different visual weights...)

Thanks all for your proposals! I'll give credits to those involved in the decision and the ones that helped with proposals.
