I wouldn't say all of the mentioned individuals are solid performers but overall, yes, AEW's priority is the WRESTLING part. Mr. Hausen would've never fit that part regardless of any gimmick he ever had
AEW's primary product is in ring wrestling.
All of the gimmicks you mentioned are attached to wrestlers who can provide that, that's why they fit the product that AEW is selling.
Even the weakest in ring wrestler there is still arguably a better in ring worker than Danhausen
