How can you point at something which is not longer applicable?

No. They are NOT part of this series. Prerequisites are seperate
entities and your series can be based on them.

So for one you want to make sure that the prerequisites for your IDXD
stuff are going to be merged into the relevant maintainer trees.

To allow people working with your stuff you simply provide an
aggregation git tree which contains all the collected prerequisites.
This aggregation tree needs to be rebased when the prerequisites change
during review or are merged into a maintainer tree/branch.

It's not rocket science and a lot of people do exactly this all the time
in order to coordinate changes which have dependencies over multiple
subsystems.

Thanks,
