Most codebases that ban exceptions do it because they parrot Google.

Google’s reasons for banning exceptions are historical, not technical. Sadly, this decision got enshrined in Google C++ Style Guide. The guide is otherwise pretty decent and is used by a lot of projects, but this particular part is IMO a disservice to the larger C++ ecosystem.

I agree. I've worked on large C++ code bases that use exceptions, and they've never caused us any real problems.
