I know some people who do videogame preservation who are watching this kind of stuff pretty closely. Although preserving original media and devices is often preferred, that can be problematic to rely only on. Disks degrade, old machines are difficult to keep in working order (especially if used by too many people) and find replacement parts for, etc. So for some use-cases being able to dump a disk/ROM/etc. image and being able to run the preserved software on an emulated device provides more reliable archival that's less likely to literally bit rot. But that has to be both possible to do, and legal to do.
