The following software related post has been marked as off-topic: How can I set up en passant in Popeye engine?
The "specific"? reason given is that "the question does not appear to be about chess within the scope defined in the help center". This tells me no more, but at least I get to look at the scope, and see that software is only marked as one of the various grey areas in chess.stackexchange scope.
Therefore, any vote for putting on-hold of a grey area matter should reasonably include an indication of why the question was seen by the individual moderator as inappropriate. Otherwise we learn nothing from the whole process.
More broadly, one of the big success areas of stackexchange is to give detailed answers to pointed questions how to use technology, and it seems odd to exclude this usage in the chess area, which uses software tools so heavily.
So: reflection rather than reflex please.
