Not enough information available yet. If only a few are found, maybe. Or maybe the TPGs will give 70s to heavily-hairlined coins because "that's the way they're supposed to look", and then nobody will care about hairlines, because a 70 is by definition "perfect". (Excuse my dripping sarcasm...)
I checked all my sets. I found no hairlines. I mean compare to those pictures posted. Those so called hairlines coins were terrible. But I do not have it. I used 10 x magnifying glasses.
