The final bend in the vertical plane would require a specific length punch to fit inside because of the very small gap (the die could still be full length). If you opened that up so that a full length punch of some thickness would fit then (I know 1/2" would work but possibly 1/4" are available over the length of the flange) you could use standard tooling on any press brake.
Another reason is you will need a bit of clearance for spring back when it gets bent. It's bendable as is, if the shop has sectionalized punches but as Gary pointed it, it would make it a bit easier for the shop. Although, sectionalized punches are pretty standard. I might put in a relief where the bends meet.
