I agree, I mean when you think of Jurassic Park you think of the T-Rex and the 1st movie, fair enough JW grossed more but JP is more iconic I think which I why completely changing it to JW would not go down well.
I personally like the ride a lot, it's pathetic but I love it maybe its because I grew up with it so it's just a ride I always head for, it usually has a short wait time too.
Though I find it hard to believe they haven't got rid of it yet.
