Part of the potential gain with containers is that you don't have to treat them like full os environments, and don't have to worry about administering them as such. I'd rather have a few tens of simple, single-process containers logging to a shared collector (or to their stdout, which is then collected) than deal with managing logrotate for them all and solve processing all those files for every host somehow.
