I have to drop the ball on this, because I don't feel qualified nor
motivated enough to follow you on this road (especially not qualified

Also, if a non-negligible percentage of peoples have problems accepting
even just GNU make as a requirement over plain vendor make, I'm not sure
how your theoretical new-generation build tools would be greeted in

All of this is not to belittle your idea, that should be clear -- it's
just that IMHO it sounds quite ortoghonal to the ongoing discussion.
