We must be very cautious when migrating questions to SE sites, because the users of the destination SE site don't want to receive questions not perfectly relevant. For the record, the migration path to https://softwareengineering.stackexchange.com/ was removed exactly because it was a source of too much "garbage".
Personally, as someone who don't play Code Golf, I wouldn't take the risk to send them something that maybe they wouldn't welcome.
And different SE sites not only accept different kind of questions but also provide different kind of answers, which may not be what the asker wanted. The question here seemed to be "Is it possible to do it ?" which doesn't seem to me the typical Code Golf challenge.
Maybe this question could have been salvaged by a passing Code Golf user but I don't think SO users have to know the FAQ and usages of all SE sites. Our job was to close this question clearly out of SO's field. Salvaging it is secondary.
