We're not using koji so I don't know how I could make use of these
repos.

I've done a number of the easier builds now and they went well. Now I'm
trying to build a package which requires imake but I can't find it
anywhere.

I guess imake could be missing because the Xorg stuff is being built
without it today?

Does anybody know if imake is still used but not shipped or is it not used
and built for EL9 anymore?

Thanks,
Simon

imake is not included in EL9 at all.  It could be packaged and added
to EPEL9 for those interested in doing so.
