Wheel truing machines back-when required Zero side-play at the hub w/o QR compression, mfgs provided that for OEM wheel builds at the factory SOP.
It was up to the mechanic at the shop on higher-end bikes to re-set for "just a touch" of side-play for proper QR compression and a smoothly spinning wheel.
Did that always happen?
Of course not, the results of running a slightly tight set of hubs out of the box and indifferent maintenance in the intervening time >40 years on are mixed at best.
Caveat Emptor.
On re-builds you have the chance to do it properly, which does take practice.
Does that "matter" in "performance"? You decide.
