After a few years of being available, there only ended up being one user of this, so it is clear that logd's duplicate message mechanism is the favored solution. The one user of this rate limiting is questionable as is, since due to the nature of storaged, the mainloop only runs once per minute by default as is, so there is essentially nothing to be gained by rate limiting any further.
