Why aren't people talking about OrioleDB (new Storage Engine for PG)?

I came across this OrioleDB https://github.com/orioledb/orioledb and by reading its description it seems to (once ready) improve a lot of key aspects of this (already great) Relational Database that is PostgreSQL. (The only missing part, IMHO is a native and optimized temporal data structure, like Datomic's EAVT and VAET).

Please, how is the community looking at OrioleDB? Is this a good thing for PG's future? Or is it just a pipe dream?

Thanks!
