It might be a good time to remind you and everyone that "film cameras were all full frame" is not how it was. Many film formats were made to find a smaller alternative to 35mm film, the most popular being 126 and 110 film sizes. These were both big sellers, and most of the big camera makers made cameras that used 110 film, including Pentax, Minolta and Fujica. Of course, the APS-C size that we now associate with crop sensors, is based on the APS (advanced Photo System) film cameras that came out in the mid to late 1990s. Nikon, Canon and Minolta all made APS cameras, not just Kodak, who introduced the system in 1996. So, the desire to make smaller format cameras has been around for many decades, so it is not surprising that it is still a popular idea for many.
