This is fixing the same issue as #3510, seems like I overlooked two cases. Note that #3528 also updates reth, but I think it should not change anything.

The post merge test currently fails to build.

Another manual run that I started as part of #3522 builds but panics:

I think this can be closed as its only commit is cherry picked to #3537, which solved AOT and has been merged. @georgwiese

I guess we can close this now?

OK, cool!
