Well, yes, but mkfs.jffs2 is there for some reason. I guess the reasons are
- speed (both of creating the filesystem and later also accessing it)
- flash wear

While I don't know it for sure I think that when created incrementally by tar (i.e extracting file by file) the result won't be as nice and compact as creating it via mkfs.jffs2 (and sumtool) in one go and then flashing. I also guess it will take ages but never actually tried.
