Antimatter - Pure Alternative

Just wondering if anybody had swapped out the Pure grid framework in Antimatter for an alternative?

If so what and and why? Much as I love the elegance of Pure it seems to be going unloved at the moment and future development looks uncertain.

Antimatter only uses Pure for grids and then it’s only a fallback if the browser doesn’t support flex. Antimatter uses a very minimal custom css framework called nucleus which is intended to be built upon. It doesn’t force a lot of style in you.

Wow, I never caught that. Going to have to dog a bit deeper. Thanks
