Thoughts on Foundations Set Constructed

Out of curiosity, is there any interest in the idea of a format solely consisting of Foundations? As someone disillusioned with WOTC over UB in Standard & Pioneer, Foundations Set Constructed seems like a good format for preserving the game's identity while simultaneously being super accessible to newer players. Though the very small card pool is a bit of a downside, there are already several archetypes (Rx Aggro, Wx Control, GUx Ramp, Cat Aggro, etc.) that look like they can be built from this pool.
