Procedures change over time. That's been a constant in the computer era.
Remember when GIFs dominated virtually all online images? When was the last time you saw one that wasn't animated? JPEG and later, PNG, replaced static images.
YouTube spent over a year translating every one of their videos to MP4 so they could run directly under HTML5 and ditch any reliance on Flash, Shockwave or any other older video playback add-ons that would no longer be allowed to run in a browser.
When I started doing work for my main client (recently retired), everything was shot digitally. My job was to take those and do any requested retouching, convert them to CMYK and then save them as an .eps. Usually with a clipping path. That was standard for about 10 years. Then they didn't want .eps files anymore, or anything converted to CMYK. For the next 15 years, everything was left as RGB, outlined as necessary, then the background dropped to transparent. All images were saved as a single, floating layer PSD. And that's how they went into their InDesign documents. All vector art that used to be EPS was converted to PDF or left as an Illustrator .ai file, and then were also used directly in InDesign that way.
Another major strike against EPS files is they've become a vector for malware. They're encapsulated data, so any attempt to do anything with them requires reading the contents. That means any embedded malware must also be read and run before you know it's there.
