I just remembered that Apple shipped an Intel Mac Mini 2020, it was literally identical to the 2018 with just the base SSD being 256GB instead of 128GB. Is Apple really supporting one but not the other? I'm pretty sure I have a 2020 somewhere…

@paul I don’t think there was an Intel Mac mini in 2020, at least not according to Apple’s “Identify your Mac mini” page, https://support.apple.com/en-us/102852

The only Mac mini in 2020 was the M1, as far as I recall., but I could be entirely wrong.

@paul I think they might have dropped the 128GB option and started with 256GB, because they did sell both intel and Apple Silicon for a while.
@waynedixon @paul The Intel Mac minis Apple sold in 2020 were still the 2018 revision, just refreshed with more storage.
