Studying EE in the late nineties, I can remember coming across EPROM microcontrollers a few times, but definitely not in new projects.
IIRC, students recently graduated when I was doing my freshman year had used them for projects in their freshman year, but not since - so they were probably commonplace until 1990 or so. At least in Trondheim, Norway.
I just flashed (literally, shined UV light through the window) and reprogrammed a few EPROMs on a pair of HP 83623a signal generators yesterday to facilitate moving a module from one, where we didn't need it, to another, where we did.
Industrial equipment moves at a different pace, and in these days of 10x price jumps and "52 week" lead times, sometimes dusty relics from the 80s wind up being relevant in 2022!
