It won't effect those bowlers at all. Only lane conditions will really have the most impact. High tech equipment is here and you cannot turn the clock back. But you can demand that there be certain units of oil in certain places at certain ratios. But then you'd make all the older houses replace their older less technically advanced oil machines and purchase tape reading machines to make sure the oil pattern meets specs. Right now, there are a ton of houses that cannot have sanctioned Sport Leagues because they do not have the equipment (or the knowledgable personel) to make sure the oil patterns meet the requirements.
And how would you police something like this? How are you going to police the proposal (that failed) that all CGs be within 1 inch of the midline. Associations are already stretched to the limit making sure that existing specs of 3 units of oil be on the lanes at all times (on a yearly basis and zero lineage every 40 days). There's just no way that you could find a volunteer body large enough to sanction every league for oil pattern specifications. So in reality the lane conditions are not feasable either.
Maybe they could go back to more bottom heavy pins. It'd be a lot easier to police those specs as there are not that much variety in bowling pins. But then when they had the heavy bottomed pins the scoring pace and participation dropped, they allowed pins to be lighter and the center of gravity higher. The scoring pace increased. Now USBC (then ABC) wants to slow down the scoring pace. I think they should make up their minds. When participation drops from any near future changes are they then going to back pedal AGAIN and change specs to increase scoring?
