It's understandable that individual files would be slightly larger in aggregate than a single combined file, due to the compression issue that was mentioned. However, since there is no more head-of-line blocking the overhead of an extra few bytes should be negligible compared to elimination of round-trip delays. Also, if you are expecting to serve HTTP1 clients for a while it's a good idea to use a hybrid approach where you combine files, just less aggressively than you may have in the past.
