- by making it out of SS, you use the same sort of welding techniques/filler rods as you would for the final rocket, which is useful and gives them experience
- they can start building up their SS supplier relationship
- SS has different physical properties as other steels, and is only marginally more expensive than the closest non-stainless alternative. using SS then verifies whatever modeling they've already done on the structure and stuff
- the high reflectivity could mess with the radar sensors or tracking equipment; so they can work out those potential issues early.

Just some thoughts I had.
