Not going to happen. All the tech working groups in the foundation report up through Yunsup who's the benevolent tech dictator for life. Changing the spec wouldn't go through without his approval. And compressed instructions check a check box in the low end cores SiFive is selling. Code density is pretty crappy otherwise. Or at least it's crappy compared to 8051s which is where they're competing against in some corners. The low-end RV16 or RV32 are a little more competitive against Cortex M0/3/4s, but even then only when you have the compressed instruction extension.
