I use Manjaro on two everyday machines, and when I did a quick google I found Arch support for the Pi Zero W which I ordered.
Digging deeper, I now see the following with respect to Manjaro:
In early 2017, This ZDnet article said:
The Manjaro ARM distribution for the Raspberry Pi 1 and Zero comes in three variations - Minimal Edition, Server Edition and Media Edition.
[Perhaps I also saw this article when doing purchasing research for the Pi Zero W]
In March 2018, Manjaro-ARM was relaunched, but support was dropped for the Raspberry Pi 1.
Manjaro-ARM does not support Raspberry Pi Zero’s (armv6h) at this time.
(The Raspberry Pi wikipedia specifications table shows the Instruction Set as
ARMv6Z (32-bit), and SoC as
Broadcom BCM2835, the same as the Raspberry Pi 1s.)
In order to hopefully attract maintainers:
What is qualifications are needed to support the Pi 1 and Zero?
Given the past Manjaro BCM2835 support and the current Arch support, what is the guesstimation on how many man hours would it take to support it again? Is there an old backlog of issues/tickets from the last time it was maintained?
I note that the Zero W adds WiFi and Bluetooth support. Given the upstream support here, what Manjaro-ification is needed (and approx mythical man hours)?
How many hours a month would be needed for maintenance?
