Nope, at the moment I am using peers only. (But I intend to switch to nested ECs in new version for object creator/editor pages, which at the moment I do in session default EC and it is not good. Are there some non-obvious gotchas with nested ECs?)
Nevertheless I _do_ put just-created objects with temporary GIDs into relationships, and it looks like there would be some problem in there perhaps :/
Thanks and all the best,
