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.

Looking at the manufacturer's site for Wylex and Crabtree, neither do the
big ones.
The full-size ones mention disconnection before testing the circuit; the
miniature ones don't.
