Ok, I tried a similar thing, no \tracingonline, but I just cat the log
file after running each of the engine with output to /dev/null.

And, the answer is that there is no \openout trace in the log with any
of the MikTeX engines. See below:


bash-3.1$ cat openout.tex
\newwrite \ourwrite
\immediate\openout \ourwrite dum.dum
\bye
bash-3.1$ for p in e pdf xe lua; do echo '====================';$p''tex 
openout.tex >/dev/null; cat openout.log; done
