I haven't seen anybody, regardless of org, procedures or whatever to never ship a bug he himself could not debug. Hell, I don't even see it happening in OS space with dozens of eyes on years-long PRs. It just happens. At some point you'll write and ship a bug that you yourself can't debug in an appropriate time frame alone and needs more eyes.
