If Fantoni-Nunes play it (as they do with1♦-3♣), then I expect it has slightly more merit than you imply. For a start as a limited bid it puts immediate pressure on the next opponent and removes a cue bid. We play the same, as we copied them (which is interesting, as this means that we are in the same circle as them in gnasher's eyes ... but perhaps only when it comes to this).
