"Implicit guarantee" is such a misnomer. The actual options are explicit guarantee and no guarantee, the latter of which has been the case all along. The "implicit guarantee" is actually just a market assumption, and the government cannot stop the market from assuming it unless they actually offer the explicit guarantee.

I don't plan on changing my current 85/15 split (in favor of the prefs) btw.
