Me, not write(2)’ing though, mostly because you don’t want to syscall-block every few bytes. Modern service managers redirect 1,2 into logging facilities (or just files if configured such way), and 1,2 are no different than 3+. As if there was a regular way for data to escape a program through non-fd (mmap/shm/fork doesn’t count).

That said I’m not sure what context we are discussing. I work on nodejs apps now where blocking is a non-issue. I’d obviously think about it more in C’s fprintf() or a similar block-by-default environment.

Edit: also, my area is fintech with $0.1-$1000 range per request, not telecom. I log everything because my employer can ask about everything, and it’s always money.
