It's not as uncommon or new as you think. Schools are often where the cutting-edge is design, and all it takes is a budget to complete a one-time project.

Before I joined NCSU in 1984, the students had already designed a 16-bit microprocessor and had it fabricated. Later students (including me) learned to program the 16-bit CPU that NCSU had designed. There didn't seem to be a steady flow of new designs or new fabrication runs, so perhaps this was a one-off opportunity.
