@Sfonxu (as we talked about it today), the key issue here is that without the change the code would not work, but the change is in a conditional branch that never gets executed on CI - which is a bug by itself. In #611, we suggest to split the example into two separate ones, so that the conditional expression goes away, and both "bin" and "bulk" code branches would be executed. Hence, suggest introducing this "split" in this PR - let's look at it on Thu.

thanks @yoctoyotta1024 for reporting it!
