This may be useful for loading GBs of data and it's quick exploration but I am wondering if there are any other uses for it besides that?

well it's as useful as any other REPL ;)

Though for things like Python the REPL serves for me mainly as a 'figure out what type this thing is here' and 'does this work'... things that static typing solve pretty well.
