Er... duh? That doesn't matter, the kind of issues we're talking about here is usually discovered via blackbox testing (not whitebox), by tracing syscalls or core API calls (no need for source access for that) as well as network communications (no need for sources either).

And the vast majority of devices are stock.

Logging has to go somewhere, logging that goes nowhere is pointless. As soon as logging goes somewhere, it can be seen and traced.
getting root access is NOT the same as looking at source code. and i don't know anyone reversed the code for IOS besides the small activation parts.
loggers could pretty much do nothing if device is not stock.
what else could be have 'too greedy logging' 'by mistake'? you and me will never know. may be nothing.
