I&#x27;d do that if I was still working there. I can probably still get hold of a horror case but it&#x27;ll take negotiation :)<p>(And yes, optimizing merge matters too, indeed it was a huge part of git&#x27;s raison d&#x27;etre -- but, again, one usually merges with the stuff at the tip of tree: merging against something you did five years ago is rare, even if it&#x27;s at a branch tip, and even rarer otherwise. Having to rewrite all the unmodified ancient stuff in the weave merely because of a merge at the tip seems wrong.)<p>(Now I&#x27;m tempted to go and import the Linux kernel or all of the GCC SVN repo into SCCS just to see how big the largest weave is. I have clearly gone insane from the summer heat. Stop me before I ci again!)
