I still have two critical machines that are v1 (old Intel Atom CPUs).
They are my local routers/NAS servers (primary and secondary). One is
even pre-UEFI. They still work fine and do their job great. I don't
mind if some applications I couldn't run on them anyway start requiring
v2, but having the whole distro switch to v2 will prevent me from
running Fedora on these two.
Yes but at some point we need to do the cut and not being held back by old / ancient hardware forever.
