No, it’s simply inconvenient for a really small group of people. People who are probably tech savvy enough in an hour to write a script to use Ghostscript to convert every postscript or eps file in their library to pdf.

I spent nearly 25 years in print publishing tech (up until 2015) and it was rare for the last 3 years of my tenure in that industry to see any postscript source files for anything. The industry that postscript was built for moved on nearly 10 years ago.
