Do themes and concepts from variants in this post concern like those on ICC: bughouse, crazyhouse, giveaway, Three Checks, Losers, etc.?
Who is the addressee of this question? Interpreting the header of the thread, probably created by Smyslov_Fan, the term "draw death" seems to suggest that we're discussing "serious" chess variations, but as it's not "my" thread, I can hardly stipulate its topics.
-----------------
Coming back to Yedidias suggestion (cf. post #19, brought up by dfan), it again seems to be a "give-and-take"-situation. Take a variation like the bishop sacrifice in the Slav (1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 6.Ne5 e6 7.f3 Bb4 8.e4 Bxe4 9.fxe4 Nxe4). I consider this an interesting fighting variation, and it would be a pity if it wouldn't be playable any more. But that seems to be the case, if Yedidia's proposal would become reality, as White has (instead of the "fighting" 10.Bd2) also the meek 10.Qf3. It would follow 10...Qxd4 11.Qxf7 Kd8 12.Bg5 Nxg5 13.Qxg7 Bxc3 14.bxc3
Qxc3 15.Ke2 Qc2 16.Ke1 Qc3 with a perpetual. So far, so good, no reason for Black to abandon this variation if he isn't in a must-win-situation. But the last capture was done by Black (in the 14
th move, printed bold), so he would "lose the draw". That means that the whole bishop sacrifice variation would become obsolete. (Actually, Black has the deviation 12...Kc8 13.
Qxe6 Kc7 14.Qf7 Kc8, and now the only move played is 15.Qe6 with a perpetual; here it is White who has made the last capture. But I think White can "improve" with 15.Qf5N! Nd7 16.Nxd7 Bxc3 17.bxc3
Qxc3 18.Ke2 Qd3, again a perpetual, but with the last capture by Black.)
On the other side, variations which are (from a theoretical point of view) not playable for White, as Black has a draw in hand, might become acceptable, if Black's draw is only achievable by him "doing the last capture". I have no example at hand at the moment, but I'm sure there are many such variations out there.
