I mean, I'm assuming that as a default, if we know someone is continuing with TT/AJ then sure, but I don't think that's a reasonable assumption without a read.
I'd rather 4bet something with blockers that I don't mind being shoved on with - AXs, that sort of thing - if he flats, we have ways to make something nutted, if he shoves it's an easy fold. 4betting QQ here I think just wastes the value of a hand that we don't really want to call a shove with absent reads, and which, if he flats a 4bet, we rarely improve and more importantly don't flop any additional equity to continue aggression.
