yeah you can say that. It's a gimmick, if you watch high level jacqui players, they are using staggers instead of feints. Thing is, in terms of frame data, staggers are way better. F3 is -2 on block and you can poke after that (completely safe), meanwhile F31 L2 is like -10, fully punishable on read, and pretty easy to do since jacqui players push buttons after the feint, so there is no chance you miss the punish if you made the read.
If you face a jacqui player that goes for feints, just practice full combo punish (usually s1 combo starter) as soon as you block f3.
Safe option is poking after you see the feint.
