Stashed diagnostics, argh, such a PITA.
Having to create a delayed bug for every single one is unfortunate. Is it possible to only do that when -Ztreat-err-as-bug is enabled? You haven't described the debugging much so I'm only guessing at what you're doing. Also a brief comment here explaining why a delayed bug is preferable to an unchecked ErrorGuarantee would be useful.

I actually like the use of span_delayed_bug over unchecked_error_guaranteed, and it's not like it's a perf issue
