The lack of detailed bug reporting is hardly limited to NVDA, and you know that as well as anyone.
But as I've said before, and Tyler confirms in other instances (but at least where something shows up), getting error tones when there is no observable error makes it impossible for someone to even write a bug report. What would it say, "Everything worked just fine, but I got an error tone?." That's why the use of such when real errors have not actually occurred, or are at a level that the end user could never hope to document or influence, they're a terrible idea.
I'd also hope that NVDA, like most modern software, includes telemetry to report "silent error" conditions.
