PICT is a tool to allow pairwise combinatorial testing (http://www.pairwise.org/index.asp), meaning that, given some axis, it will find the smallest set of combinations that ensures that all pairs are tested.
I gave it a quick try with the cocoa repo and providing this input:
This is still slightly longer than the enabled configurations in the current matrix (41 vs 39), but the input file could be improved providing constraints that would allow to further improve the result.
