Yeah it seems like when you use it as a crossup against a standing opponent it's punishable by grabs, I don't think close normals can punish it. Against grapplers you can use the same mixup, but I would suggest EX dp+K in the air for that crossup, since you can easily confirm with the second hit and then make yourself safe or land another hit with the third hit.
Inadvertently I've found that against tall characters you can do j.D and cancel it into dp+B on block and it'll actually hit j.D on one side and dp+B on the other, making it a ridiculously ambiguous crossup.
