Was it? Once scale problems is gone -- you assume that all code can be checked out on one machine, and you have enough buildfarm to build all the code -- the most of the article's points no longer apply. The downsides which still apply are Upside 3.3 (you don't deploy everything at once) and Downside 1 (code ownership and open source is harder). And those are pretty weak arguments -- I would argue that deploying problems exists with polyrepo as well, and there are now various OWNERS mechanisms. The fact the polyrepos are harder to open source is a good point, but having to maintain multiple separate repos just in case we would want to opensource one day seems like sever premature optimization.
