Redoubling is very useful in competitive auctions, sometimes overcaller wants to show that he has a real opening or partner of the overcaller wants to show that he has some useful stuff but no fit (8 points with doubleton support is more or less ideal).
... and I can prove it with my usual, flawless logic.

Use XX as the start of a transfer ladder, at low levels. You gain an additional 2-level raise, and you gain the transfer benefits (can show a bad hand, good suit). Some use 1NT as the beginning of this ladder, but prefer to lose the 'natural' XX to the natural 1NT. Use it as responder ... 1H (X) XX, and as advancer (1C) 1S (X) XX.

After this auction (1C) 1S (X) ??;

XX = clubs (best to skip 1NT in these ladders, they being somewhat situational)
1NT = natural
2C = diamonds
2D = hearts
2H = constructive spade raise
2S = competitive noise

After 1H (X) ??;

XX = spades
1S = clubs
1NT = natural
2C = diamonds
2D = constructive heart raise
2H = competitive noise
