I've always thought it would be nice to have a stripped-down version of make universe (make galaxy?) that compiled for a representative sample of platforms, and with only one or two kernels per platform instead of 3 or 4 or 5. For small changes, this represents a better tradeoff in time spent compiling vs. the cost of things breaking occasionally. For actively developed platforms, breaking the build wastes lots of people's time; for everything else, there's tinderbox.
