The reason why that is done in OE (as opposed to why OM should or should 
not do it) is because OE is used for devices with 8MB total of internal 
flash for kernel, modules and full rootfs.  In that environment, you 
want them to be as granular as possible so you don't waste jffs2 space.

Of course, the GTA02 is not such a device, although some people may want 
to use jffs2 space for applications rather than a bazillion kernel 
modules that they will never use ...
