I'd agree that a production system that actually relies on actual floppies would be rolling the dice in a deeply uncomfortable way at this point; but I'm a little puzzled by the extent of the fuss given that(admittedly, more for hobbyist and niche stuff, retrocomputers and synths from the floppy era, that sort of thing) the practice of emulating floppy drives is quite well established and, thanks to the age and (low) speed of the busses in question, pretty technically undemanding.
If I had a floppy-dependent system I'd have wanted people evaluating commercially available floppy emulators starting 10 years ago; potentially trying to push specific developments if my system requires things that the retrocomputing guys don't(whether in terms of features or in terms of not being hand-built in small runs by hobbyists); but, barring some especially esoteric complication I'm not thinking of, slapping floppy emulators into a floppy-based system and bringing it right up to the present day in terms of media seems like it would be both a relatively simple project and much, much cheaper, lower risk, and more predictable than a full 'upgrade' that promises to rip out the old system and replace it with a full new glorious IoT something something.
