yes that is a small concern. but the questions i posed above are more important imo.
if you 3bet AK just because he min-raised you are making a clear mistake. you need to have a plan and understand why you are 3betting. you 3bet for value and so that you can comfortably call a 4bet shove against a loose range (if you suddenly get a snap shove from the OR what do you do? obviously you cant 3bet/fold but you just isolate yourself against a very tight range if you 3bet unknowns).
if you just blindly 3bet because you want to thin the field you are definitely going to be getting into some very bad situations. playing a multi-way pot with AK isnt the best, but id much rather play 3 or 4way with position than blindly bloat the pot without any reason or reads behind it. and 3betting to isolate isnt a strong enough reason for me to 3bet.
I still think 3betting is profitable on this limit because many unknowns will call a 3bet and fold to a cbet, but IMO playing a smaller pot with position and a drawing hand where we clearly arent comfortable calling a 4bet shove is much better.
AKs does also play a lot better multi-way compared to AKo. so if i thought it was close i would much rather flat with AKs and 3bet AKo.
STT strategy is a lot tighter compared to other forms (ie. MTTs). STTs value survival a lot more than chip accumulation. And while your early stage risk-aversion is still quite low, you need good solid reads to be able to comfortable go broke with AK pre for 50BBs. 2 years ago 3bet/calling AKo was very very standard even on mid-stakes because the 4bet/get it in ranges of the fish were so wide. It is my personal opinion that in today's games you should flat AK vs unknowns because their 4bet ranges on average are a lot tighter.
