You do of course receive a completely valid take off config warning on both Airbus and Boeing when conducting this manoeuvre. There's no difference between manufacturers in that regard.
Where has that "happened a fair bit on the narrow body Ab series", and (not that I've ever heard of it, but) even if you did retard the T/Ls, isn't it wheel spin up, plus WoWs that triggers spoiler deployment? I no longer have my Airbus books, but how would that "hasten your downward progress"? I'm afraid I'm not following? Is it just because the wheels are spinning, with no WoWs requirement?? I genuinely can't recall.
Cheers
