This sounds like a nice starting point to me as an additional way
to run tests upstream.  I have one particular question as I see a
pattern through the rest of the email, please see below.

Where does this fit on the KernelCI roadmap?

I see it mentioned a few times but it's not entirely clear
whether this initiative is an independent one or in some way
linked to KernelCI.  Say, are you planning to use the kci tool,
new API, compiler toolchains, user-space and Docker images etc?
Or, are KernelCI plans evolving to follow this move?

Thanks,
Guillaume
