I just had a question on stackoverflow closed as not constructive. I'm interested in why it was deemed as not constructive. I was asking why a seemingly obvious flag had not been included in Git's commit command as I was certain that there must have been a good reason, but was interested in what that was. In most of the cases I have seen a question closed, the reason was obvious, but I can't see how this was an unconstructive question.
I'm not asking for it to be reopened, just interested in why it was closed.
