Yes, and it also requires an Arch system (or at least one with pacman
available) to run mkarchiso, pacstrap, copy the initcpio configs from
mkinitcpio, etc. Which is a bit of a chicken-and-egg problem, and I
don't really consider this a viable generic solution...

Can't this be done from any distro using Arch rootfs?

Like I said, this can be done from any system which has pacman and
mkinitcpio available. That means:

1) Arch Linux
2) Gentoo, which has a pacman package and IIRC also provides mkinitcpio
   as an option alongside dracut.
3) Any Linux distribution if you have chrooted into the bootstrap image
4) Windows (or any operating system, really), by using a virtual machine

Certainly, anything is *possible* if you put in enough work. But making
something annoyingly difficult to do is, as I said, hardly a generic
solution.

True and Alpine Linux supports (3.5) ZFS on install which I didn't confirm
because, like I said, I don't use ZFS on Linux. I mean that if Arch
ZFS developers want to, they can leverage work from other distros.
I guess it's a good thing Arch has no installer or otherwise there
might be a heated debate whether ZFS should be an option :).

Well, it seems it was an issue and not just a hiccup. I posted the issue to
the linux-raid list on kernel.org (title: "4.15.8 Kernel - Strange linux-raid
behavior, not sure where to send it.") and it seems there have been other hit
with it as well:

https://bugzilla.kernel.org/show_bug.cgi?id=198861
https://bugzilla.redhat.com/show_bug.cgi?id=1552124

Thankfully, since I installed the 4.15.9 kernel, it seems to be fixed (I still
have more testing to do, but it looks good)

So if anyone else is hit with a raid 1 issue on multi-cpu boxes, there is more
information at the links above.

(p.s. - not that my opinion matters on the bug tracker choice, but for the
number of bugs Arch has (compared to Mozilla, etc.) I don't think there would
be much of a delay issue regardless which packages is used - ease of
maintenance and an easy migration path probably wins the day)
