So did I and a bunch of other folks. I for one run v1 since 2017 on a bunch of boxes (amd64/BIOS, amd64/EFI, arm64, armhf), without a glitch (not counting trying to boot zstd initrd _without_ the patchset :p). I've tried v2 on all of the above configurations, v3 on all but armhf, v4 on amd64/EFI -- all is fine. Back in the days, folks reported success on IIRC ppc64, sparc64 and more.

It's good for production machines but slows down dev cycles. But that's a matter for userland, not a problem with Nick's patchset.
