What's the point of big RCBOs?

I think the first generation RCBOs were taller, then they managed to
shrink them to MCB size in second generation, so I don't think
there's any 'point' as such to the tall ones.

The small ones often do not have the functional earth fly lead.

Apparently Chint can squeeze a 3-ph RCBO into a single-width module ...
