I can't think of a realistic situation in ASA in which it is not to the defense's advantage to appeal a BOO situation. Any outs made always stand, you always get the out for the batter who failed to bat in the proper order, and no runners can advance on the pitch that completes the improper batter's at bat.

OK. If, with none out in the 6th inning, the 6th batter bats instead of the number 2 batter and hits into a double play, and if numbers 3, 4, and 5 are great hitters and numbers 7, 8, 9, and 10 are automatic outs, then the defense might keep quiet about the BOO. Same if the improper batter hits into a triple play—the defense might choose which batter it wants to lead off the next inning.

But in NCAA, which follows OBR closely, it could well be to the defense's advantage not to appeal. Years ago the Pirates batted out of order the first 2 times through the lineup, and the Mets kept quiet until the third go-round, when the improper batter got a key hit.
