Actually I wanted to feature my little series here in your thread as one
step closer to untangling this stuff too, so ... care to review (except
for the one patch that is dropped already)?

Wrt the lists I think we should first untangle the execlit/request story,
since I expect that a few of them need to be moved to different structs.
After that it should be a bit clearer what needs to be moved where. And
then there's also the golden context and render wa init code which also
needs to be shuffled a bit (similar to this series).
