Two Q:
Do you do it? If not, doesn't that make 3-betting from the BB (versus 1 opponent) a little bit more attractive, contrary to the modern trend?
If you are played back at, auto-calldown?
Sample:

SB: 14.2 BB (VPIP: 33.74, PFR: 0.93, 3Bet Preflop: 0.00, Hands: 327)
SB posts SB 0.2 BB, Hero posts BB 0.5 BB
Pre Flop: (pot: 0.7 BB) Hero has A♥ K♣
fold, CO raises to 1 BB, fold, fold, Hero calls 0.5 BB
Flop: (2.2 BB, 2 players) 9♥ 5♠ 5♦
Hero checks, CO bets 0.5 BB, Hero raises to 1 BB, CO raises to 1.5 BB, Hero calls 0.5 BB
Turn: (5.2 BB, 2 players) Q♥
Hero checks, CO bets 1 BB, now what?
My chances are that he is bluffing. If not, I just barely do not have odds and outs to go on.
