For myself, I think it's reasonable to conclude there's a non-trivial amount of people using QEMU on that hardware in some fashion. Much of that is probably from podman as opposed to running large virtualized environments at this point, but the podman use case is important for a lot of people.
Without knowing which CPU models are actually affected, I don't think it's reasonable to draw any conclusions.
For personal anecdote: my oldest system I still use for anything is a 7-year-old Intel NUC (i5-7260U), and it's actually v3. My lowest-end system is a router (not running Fedora); it's a Pentium N6005 and appears to be v2 (it doesn't use glibc, but I found an awk script that seems to report it).
So yeah, it may be time to say "okay, we can't run QEMU on the old systems anymore". If upstream QEMU is going to make their software v2+ only, that's really the only reasonable conclusion; it is not reasonable to demand Fedora packagers maintain a patchset or a fork to revert that change.
But again, knowing what CPU models are what level would bring more clarity to the effect. I don't know how to look at say Intel Ark (does AMD have a similar site?) and determine "this CPU is v3". IIRC when the baseline came up before, the only current or recent CPUs that weren't v2+ were some Intel Atoms.
I've looked at a few Atom, Apollo Lake, and they're v2 (I have a couple of others to boot to check), most Atom are not v3. I have an AMD platform (AMD Turion(tm) II Neo N40L Dual-Core Processor) that is v1, but it's certainly not something I run virt on any longer.
