The Microscaling paper and the following MX OCP spec is along the lines of what you call batch floating point, though I believe the original 1963(?) work on it called it "blocked" floating point. Datatypes are really tricky. Hardware designers tend to be conservative in my experience, and don't want to waste die space on things that might not be useful.
