One side effect is that it will remove the older copies. The older
copies were being built into each new sstate object which was growing
huge.

You'd need to archive them before running another build since this
effectively cleans up the older copies now. This is due to the system
removing the old sstate "object", then installing a new one to replace
it. You can't keep the old ones around easily as they're named to
conflict (and hence replace each other).
