Why did stocks choose EPS 10 as the gold standard?

Question

EPS

Why did stocks choose EPS 10 as the gold standard and still not accept older versions of EPS files? Although more than 10 years have passed since they introduced this gold standard, and new versions of EPS files appear every year. Are they really that useless compared to him? And why are they needed then?

Answer 1

Perhaps because old versions of programs will not be able to open new versions of eps. And new versions of programs will open any version.
