There are a lot of turns (i.e. this one) where a guy with AA/KK will slow down on the turn if I 3b the flop. JJ-88 also can get away cheaply.

JJ-88 get away cheaply when you b/c, c/r (they should at least since this line is ~never a bluff). everyone shows down JJ-88 when you 3-bet the flop.

vs. AA/KK you'll pretty much never get more than 3 bets on the turn and river when you take this line. on a turn blank, he will usually correctly place your hand range as AA-QQ. on a 9, T, or J turn, he can include 99, TT, or JJ respectively. on a club turn, he can include AcJc, AcKc. there's just no way you'll represent a hand against which he should 3-bet the turn.

3-betting the flop almost insures you making more off of AA (either he caps flop or calls and raises turn), and many will give you more action even with KK. i mean, when he calls the flop and raises the turn with AA, that's an additional 1.5 big bets compared to your line.
