I didn't consider other approaches that's all, I used it to be able directly
return "a call" to another function without thinking about it much - void works
nicely as well.

warning is the default log level and there are a number of devices withing the
system which we don't care about and if debug is enabled you'd see messages
like "Discarding device...", so by using warnings here, you'd just pollute the
logs the same way, not sure whether that's desirable, since 1) you can't tell
whether we discarded the device on purpose (which is the case most of the time)
or 2) there's a real problem with the device.

I added a handle thread in a follow-up series where the thread routine invokes
this function and I wanted to make the thread routine a few lines shorter and
"cleaner", no additional value added.
