Yes please, it's better if we can review it in the mergeable state, without the temporary things/FIXMEs.

The thing is that it's not really possible to point to a merge commit that doesn't exist before the PR is merged. So I don't see this happening at this stage. That's effectively why I created this PR as a draft.

But that doesn't matter anymore since it looks I'll have to abandon the cross-repo reusability bit for now.
