The reason why we had that flag was because some of the older devices didn't have enough partition space on the system to include all the system webapps on the partition and we needed a way to push it to the data partition instead. ( https://bugzilla.mozilla.org/show_bug.cgi?id=1066005 )
By default, I think the B2G_SYSTEM=1 at least for PRODUCTION=1 : http://mxr.mozilla.org/gaia/source/Android.mk#24 The reason why we decided against not having system apps on the system partition is that reseting the device would wipe out all the system apps as it wipes out anything in the userdata partition.
