While there will be a significant amount of work to change the way our bots work here at Apple, the work is not impossible to accomplish. Given the choice, I would of course prefer an approach such as Paulr has suggested. The ability to run things in parallel for a time provides for a much lower impact change on the entire community. I think this approach may also give us some time to decide where the debuginfo-test should fit in the new mono-repo. It would be a bummer to do the work necessary to make this change, only to discover we would have to do it differently in the not too distant future to accommodate the new mono-repo.<br class="">
