This feature same request Add softwarerecs to vote to migrate option was declined in Feb. 2014, since the circumstances meanwhile changed I don't think this is a duplicate.
Software Recommendation graduaded and has 3 elected moderators now it should have become a valid migration target
You will become eligible for question migration paths with the rest of the network
As stated by Gilles:
Super User generally rejects recommendation questions (which is the primary reason why the Software Recommendation site exists in the first place), so your question was by no means “perfectly reasonable” there. Rather than being closed in place, your question was migrated here where it is on-topic.
There is a plenty of well phrased and even researched questions which would for sure be welcome on Software Recommendation instead of getting downvoted and just closed on Superuser.
