rule book also says that player failing to make moves in allocated time loses. So winning with time is just the same. And bullet this just amplifies. If you for quality of moves use longer time controls
6.2 a. When using a chess clock, each player must make a minimum number of moves or
all moves in an allotted period of time and/or may be allocated an additional
amount of time with each move. All these must be specified in advance.
6.9 Except where one of the Articles: 5.1.a, 5.1.b, 5.2.a, 5.2.b, 5.2.c applies, if a player does
not complete the prescribed number of moves in the allotted time, the game is lost by
the player. However, the game is drawn, if the position is such that the opponent cannot
checkmate the player’s king by any possible series of legal moves.
That is from the rulebook and clearly tells that putting opponen in position to not complete all his/her moves is just an another way of winning. And in short time controls it is pretty normal.
