Hello,

Here is what I get:

bash-3.1$ cat > openout.tex <<EOF
> \newwrite \ourwrite
> \openout \ourwrite dum.dum
> \bye
> EOF
bash-3.1$ pdftex openout.tex
This is pdfTeX, Version 3.1415926-2.5-1.40.14 (MiKTeX 2.9 64-bit)

As you can see there is no such thing as any \openout trace in the .log
file, for any of pdftex, luatex or xetex engines.

I fully agree with the argument by Karl: even though the --recorder
option now exists on most engines, we should not break the world.

However it is rather easy to check whether the --recorder option is
supported like that:

bash-3.1$ if pdftex --recorder '\bye' > /dev/null; then recorder_support=yes; 
else recorder_support=no; fi
bash-3.1$ echo $recorder_support
yes
