It's definitely not something for everybody, and I suspect not really a "revolution" outwith the dedicated enthusiasts segment of the population. (-:
If one wasn't likely to have a rack of desktop PCs at home, one probably will be hard pressed to have a reason for a collection of mini PCs.
On the other hand, there are a few more use cases than just over-egging a light switch or being a big file server. One can replaced dedicated hardware such as network gateways/routers, and do self-hosting, for examples.
There are RaspberryPi systems that one can get with extra Ethernet ports that can be set up to do application gatewaying and routing with general-purpose operating systems like FreeBSD, NetBSD, and such. And obviously filtering HTTP/other proxies incorporating spam/advertising/malware blockers are a well-known use case.
There are oddball mini PCs in some parts of the world with loads of serial ports, useful as terminal hosts if one has a lot of systems with no disploy/HIDs. (I saw one mentioned on the FediVerse the other day. It turned out that it was an old Russian point-of-sale system, with 6 serial ports.) More of a use case for someone who already has lots of PCs (with serial ports), of course.
But yes, it's not going to be everyone's cup of tea. Not everyone is Kitboga with a server farm in xyr garage running speech synthesis engines and language models to call scammers. (-:
On the gripping hand, I swapped out someone's under-the-desk tower for a mini PC years ago simply for space reasons.
