OmitStackTraceInFastThrow has caused so many headaches in debugging production issues, and each time now the answer has been to just disable it. The real answer is to stop trying to abuse exceptions as a form of general control flow.

For some reason the most talked about "alternative" to exceptions seems to be "use optional". I would assume that this has the same debug issues as omitting the stack trace.

I don't expect so. If I "forget to handle" an optional, I get an error at compile time pointing at the lines in question. If I forget to handle an exception with an omitted stack trace, IIUC, I am told at runtime that there's an error somewhere in my program. It's much easier to debug the former.
