I can confirm, the first time I saw one of them (many years ago, I believe probably 15 years ago, maybe more) it was in the workshop of someone who provided assistance/repair to sewing machines (and embroidery machines), from what I can remember at the time floppies and floppy drives were still in use and it was intended as an upgrade as it had less issues with dust and was more convenient to have many (up to 100) "floppy" images available.

Besides the (now common) Gotek, there are every kind of emulators/replacements for industrial machines, like, besides embroidery, CNC's, some early robots, etc., here is a site dedicated to them:
