Obi,
I've cut and pasted the excel numbers below. It assumes the 5% rate is used from the start as per Cap's 491 and applying all the payments to interest / then to principal.
Once the loan is repaid; it pays Freddie $$ at 5% same as it was re-charged.

If you can put this in a spread sheet you'll see the power of compounding!
At 5% - they'd owe Freddie $18Billion!
Fannie is done and recalculated the same way. It results in a higher amount owed.
If they do this you can forget that 30 year amort thing.
Next to your question of what happens. Well that's not up to me; but i couldn't imagine they'd not be free. Also, keep in mind the tax benefit of re-characterizing this as interest payments. Freddie would have to show the expense and the tax benefit of the interest expense.
This would be great.

Enjoy.
