I think there also might be some consideration of ability to move from dev hardware to a more optimized mass market product. MiniITX boards or cellphones with I/O breakouts rely on much 'wider' supply chains with providers who have their own interests that might not be as amenable to setting up mass production with a customized version of the dev hardware 2-3 years down the line. They also probably serve as gateway products, so someone might buy this kit for a hobby project and get familiar with Xilinx's ecosystem, leading them to then have a bias towards Xilinx for when they're in the workplace having to decide on an FPGA.
