No dispute. Judging from the activity on this bug, I'm probably the only person
whom this will ever affect, so you can probaly close under "user educated."

All I can say is that it wasn't obvious to me that it _wouldn't_ work until I
did some research. Maybe the package readme file was the place to start, but
"Do not use on Debian" was not in my top search results. I try to make a good
faith effort to exhaust my options before contacting a human, so that helped me
find this bug reports.

Someone else can take up that cross, especially considering how my bug reports
get received. I saw the configuration option and thought "Wonder if I can do
it?" I don't really remember how or when I figured out that I wasn't supposed
to use it. That means I also can't remember what would have to change to learn
this earlier in my troubleshooting process.
I hope something here was useful.
